gpu: nvgpu: Use sw ops for BIOS

Browse Source 
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
