26406a070d gpu: nvgpu: Hardcode nvlink speed to 20G
Xavier Chip Product POR was updated to 20G only. No more qual work 
happening for 16G. So we do not plan to support 16G. Now that we have
a single speed left, remove the code added to support nvlink speed from
VBIOS as it is redundant.

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.

54e179ddad gpu: nvgpu: fix MISRA 13.5 nvgpu.hal.nvlink
MISRA rule 13.5 doesn't allow right-hand operand of logical && or ||
operator to have persistent side effects. The reason is right-hand
operand is executed or checked depending on the left-hand operand value.
That means side effects in the right-hand operand may or may not occur,
contrary to programmer's expectation. Hence, this rule is implemented to
avoid unexpected behavior.

This patch divides if condition with logical && operator to nested if
conditions to resolve this violation.

This struct was earlier moved to falcon_priv.h to give exclusive access
to only falcon unit. However with HAL unit needing access to this we
need to move it public header nvgpu/falcon.h.

Move the code involved in dealing with minion into a separate unit
called "nvlink_minion". This unit includes minion HW access, ucode
handling, exposing state of minion and also dealing with minion
interrupts. The interfaces to this unit are partially exposed using
g->ops.nvlink.minion ops and rest are part of nvlink_minion.h public
header.
