Previously initializing buddy_allocator with size=0 initialized large
memory block. With fixes in buddy_allocator_init() function, size = 0
triggered segmentation fault and so size was temporarily updated to
fixed value.
This patch updates buddy_allocator_init() function to return error if
requested size of buddy_allocator is zero. As kernel VMA is absent for
VGPU, this patch also updates nvgpu_vm_do_init() function to not
allocate kernel VMA with size = 0.

PG189 has multiple sensors which can provide interrupt when board
temperature reaches programmed threshold.
This Interrupt is implemented in nvgpu and provide events via clk_arb.
Support is enabled for TU104 with NVGPU_SUPPORT_DGPU_THERMAL_ALERT flag.
Board specific config is added in DT which will be parsed by nvgpu.
Nvgpu does the following.
1.Read gpio line number, interrupt type, and event delay from DT.
2.Call kernel methods and register the interrupt with kernel.
3.Create work queue which will process the interrupt in process context.
4.When interrupt occurs disable interrupt, add work to work queue.
5.In work queue post events and sleep for delay time then enable
Interrupt

Some functions are not accessing hardware directly
but are being called using HAL ops: For example
.init = gv100_bios_init,
.preos_wait_for_halt = gv100_bios_preos_wait_for_halt,
.preos_reload_check = gv100_bios_preos_reload_check,
.devinit = gp106_bios_devinit,
.preos = gp106_bios_preos,
.verify_devinit = NULL,
This was being called as:
g->ops.bios.init(g)
g->ops.bios.preos_wait_for_halt(g)
g->ops.bios.preos_reload_check(g)
g->ops.bios.preos(g)
g->ops.bios.devinit(g)
g->ops.bios.verify_devinit(g)
Change the function access by using sw ops, like:
Create new function: nvgpu_bios_sw_init()
and based on hardware chip call the chip specific
bios sw init function: nvgpu_gv100_bios_sw_init()
and nvgpu_tu104_bios_sw_init()to assign the sw
ops

MISRA Rule 11.3 prohibits casting between different pointer types. The
previous "fix" in nvgpu_bios_parse_rom() was to use an intermediate cast
to uintptr_t. However, that leaves the possibility of creating a
mis-aligned pointer. So, instead of casts, use nvgpu_memcpy() to make a
copy of the data in a local structure.

struct pointer's local variable name to page_ptr to resolve the
violation. Also, renames function "nvgpu_page_alloc" to
"nvgpu_page_balloc" to remove identifier name overloading.
MISRA rule 10.x forbids from casting value of composite expression to an
object with different essential type category. This patch replaces
multiplication operation to left shift operation.
MISRA rule 15.7 requires every if .. else if construct to be terminated
with an else statement. This patch updates if .. else if condition to

MISRA Rule 17.2 doesn't allow recursive call from a function to itself,
as this might lead to stack overflow. Updated nvgpu_page_allocator_init
to call nvgpu_buddy_allocator_init() directly.
