Switch non-CPU callers from ld/st*_phys to address_space_ld/st*
Switch all the uses of ld/st*_phys to address_space_ld/st*,
except for those cases where the address space is the CPU's
(ie cs->as). This was done with the following script which
generates a Coccinelle patch.
A few over-80-columns lines in the result were rewrapped by
hand where Coccinelle failed to do the wrapping automatically,
as well as one location where it didn't put a line-continuation
'\' when wrapping lines on a change made to a match inside
a macro definition.

Switch non-CPU callers from ld/st*_phys to address_space_ld/st*
Switch all the uses of ld/st*_phys to address_space_ld/st*,
except for those cases where the address space is the CPU's
(ie cs->as). This was done with the following script which
generates a Coccinelle patch.
A few over-80-columns lines in the result were rewrapped by
hand where Coccinelle failed to do the wrapping automatically,
as well as one location where it didn't put a line-continuation
'\' when wrapping lines on a change made to a match inside
a macro definition.
