Introduce nvgpu specific functions for bitops and bitmap operations
with unsigned integer as parameter for offset. OS specific type
conversions and handling of these inerfaces are taken care in the
respective OS files.

Move the PTE size computation from MM to VM where it belongs. This
function is only ever used in vm.c so move it there and make it
static.
This is part of the broader effort to cleanup the top level unit

Make the nvgpu_init_mutex function return void.
In linux case, this doesn't affect anything since mutex_init
returns void.
For posix, we assert() and die if pthread_mutex_init fails.
This alleviates the need to error inject for _every_
nvgpu_mutex_init function in the driver.

The vm object num_user_mapped_buffers was declared as an int. However,
it is an unsigned value. Being a signed value required a cast to
unsigned when calling nvgpu_big_zalloc() which causes a CERT-C INT31
violation. So, avoid the cast and use an unsigned type. And fix related
INT30 violations related to num_user_mapped_buffers as well.
To avoid introducing new MISRA/CERT-C violations, update the upstream
user of these changes, fifo/channel.c and make the equivalent uses of
this value, num_mapped_buffers a u32 as well.

For one case, the conditional operator was being used for s16 values
which were being promoted to ints. So, replace the conditional operator

Firmware data is also not aligned at word boundary sometimes
hence we need to copy it byte by byte to conform to the dev-
