PM / devfreq: Fix out of bounds access of transition table array

The previous_freq value for a device could be an invalid frequency that
results in a error value being returned from devfreq_get_freq_level().
Check for an error value before using that to index into the transition
table.

Not doing this check will result in memory corruption when previous_freq is
not a valid frequency.

qseecom: Add basic suspend resume functionality

If ce clock is not disabled in suspend state, memory may be corrupted and
device can not wake up. Thus,if clock is enabled, we disable it in qseecom
suspend function and re-enable it again in resume function.

msm: peripheral-loader: Change IOMAP_SIZE from SZ_4M to SZ_1M

The ioremap call made for zeroing out trailing memory is currently
requesting for a 4M memory region. This is resulting in vmalloc
allocation failures on some platforms.
Instead, request for 1M memory locations and zero out the area
in smaller chunks to make this failure less probable.

uio: provide vm access to UIO_MEM_PHYS maps

This makes it possible to let gdb access mappings of the process that is
being debugged.

uio_mmap_logical was moved and uio_vm_ops renamed to group related code
and differentiate to new stuff.

regulatory: use correct regulatory initiator on wiphy register

The current regdomain was not always set by the core. This causes
cards with a custom regulatory domain to ignore user initiated changes
if done before the card was registered.
