80f10bcc7f staging: rts5208: Replace pci_enable_device with pcim_enable_device
Devm_ functions allocate memory that is automatically freed when
a driver detaches.

Replace pci_enable_device with pcim_enable_device. Remove unnecessary
pci_disable_device and pci_release_regions from probe and remove
functions in rts5208 driver since pcim_enable_device contains a call
to pcim_release which contains calls to both pci_disable_device and
pci_release_regions.

For 6-byte r/w commands, transfer length 0 means 256 blocks of data,
not 0 block.

d5a7d45fb5 Staging: rts5208: Replace timeval with timespec64
struct timeval tv is used to get current time.
32-bit systems using 'struct timeval' will break in the year 2038, so
we have to replace that code with more appropriate types.

8ee775f92c staging: rts5208: Remove RTSX_READ_REG and RTSX_WRITE_REG macros
Macros with hidden flow control are bad form as the code path
taken can be unexpected for the reader.

Expand these in-place and remove the macros.

Done with coccinelle script:

031366ea65 staging: rts5208: Remove TRACE_RET and TRACE_GOTO macros
Remove these flow hiding macros.

Miscellanea:

o Add a macro and function to replace a large inline
o Simplify #includes
o Add trace.c and update Makefile
o Remove static inline filename function and use kbasename instead

This reduces object size quite a lot: ~350KB (x86-64 allyesconfig)
