f4ec400d5f gpu: nvgpu: simplify nvgpu_timeout_init
nvgpu_timeout_init() returns an error code only when the flags parameter
is invalid. There are very few possible values for flags, so extract the
two most common cases - cpu clock based and a retry based timeout - to
functions that cannot fail and thus return nothing. Adjust all callers
to use those, simplfying error handling quite a bit.

3c7cf8b75a gpu: nvgpu: fix MISRA 10.5 issue in timeout code
This change switches nvgpu_timeout_peek_expired() to return a bool
instead of an int to remove advisory rule MISRA 10.5 violations.

MISRA 10.5 states that the value of an expression should not be
cast to an inappropriate essential type.

20fcf813dd gpu: nvgpu: Use sw ops for BIOS
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
