For frontends with ISDB-T, DVB-T2, CMDBTH, etc, some code is

Get rid of using ops->info.type defined on DVB drivers,
as it doesn't apply anymore.
Currently, one driver (cxd2820) supports more than one different
info.type, as it can be used for DVB-T/T2 and DVB-C. There are more
drivers like that to come. So, the same frontend will have
different DVBv3 types, depending on the current delivery system.
This breaks the existing logic at dvb_frontend, that assumes that
just one delivery system DVBv3 type is supported by all delsys.
In order to easy the DVBv3->DVBv5 conversion, an ancillary function
that maps DVBv3 delivery systems into DVBv5 were added.
Also, on all places, except for the event logic, the DVBv5 cache
will be used to check parameters, instead of the DVBv5 copy.
This patch simplifies the cache sync logic, and warrants that the
cache will be in a clear state at DVB frontend register. This way,
ops->info.type will be filled to reflect the first delivery system,
providing backward compatibility support for it.
For example, in the cases like cxd2820, where the delivery systems
are defined as:
.delsys = { SYS_DVBT, SYS_DVBT2, SYS_DVBC_ANNEX_A },
A pure DVBv3 will be able to use both DVB-T and DVB-T2, as, at
DVB cache clear, the ops->info.type will be equal to FE_OFDM.
However, DVB-C won't be visible. A quick workaround would be to
do a DVBv5 call to set the delivery system to SYS_DVBC_ANNEX_A.
After such call, ops->info.type will be equal to FE_QAM, and a
DVBv3 application will see the frontend as a DVB-C one.

This change is there in order to prepare the code to avoid calling

This reverts commit 93b2ec0128.
The call to "schedule_work()" in rtc_initialize_alarm() happens too
early, and can cause oopses at bootup
Neil Brown explains why we do it:
"If you set an alarm in the future, then shutdown and boot again after
that time, then you will end up with a timer_queue node which is in
the past.
When this happens the queue gets stuck. That entry-in-the-past won't
get removed until and interrupt happens and an interrupt won't happen
because the RTC only triggers an interrupt when the alarm is "now".
So you'll find that e.g. "hwclock" will always tell you that
'select' timed out.
So we force the interrupt work to happen at the start just in case."
and has a patch that convert it to do things in-process rather than with
the worker thread, but right now it's too late to play around with this,
so we just revert the patch that caused problems for now.

If one only selects mx23-based boards, compile fails:

drivers/net/ethernet/freescale/fec.c:411:2: error: 'FEC_HASH_TABLE_LOW' undeclared (first use in this function)
This is because fec.h uses CONFIG_SOC_IMX28 to determine the register
layout of the core which makes sense since the MX23 does not have a fec.
However, Kconfig uses the broader ARCH_MXS symbol and this way even
makes the fec-driver default for MX23. Adapt Kconfig to use the more
precise SOC_IMX28 as well.

Just like set_frontend, use the dvb cache properties for get_frontend.
This is more consistent, as both functions are now symetric. Also,
at the places get_frontend is called, it makes sense to update the
cache.
Most of this patch were generated by this small perl script:
while (<>) { $file .= $_; }
if ($file =~ m/\.get_frontend\s*=\s*([\d\w_]+)/) {
my $get = $1;
$file =~ s/($get)(\s*\([^\,\)]+)\,\s*struct\s+dtv_frontend_properties\s*\*\s*([_\d\w]+)\)\s*\{/\1\2)\n{\n\tstruct dtv_frontend_properties *\3 = &fe->dtv_property_cache;/g;
}
print $file;
Of course, the changes at dvb_frontend.[ch] were made by hand,
as well as the changes on a few other places, where get_frontend()
is called internally inside the driver.
On some places, get_frontend() were just a void function. Those
occurrences were removed, as the DVB core handles such cases.

The cx23885-dvb driver has a dirty hack:

2) it uses internally the DVBv3 struct to decide some

Replace it by a change during the gate control. This will
likely work, but requires testing. Anyway, the current way
will break, as soon as we stop copying data for DVBv3 for
pure DVBv5 calls.
