Different SKUs may require different nvlink speed and hence the
nvlink speed value should come from VBIOS. The initpll number
corresponding to speed is present in VBIOS Low Power Nvlink table
header. Parse this data from VBIOS and set corresponding nvlink
speed and minion initpll DLCMD as default.
We can no longer update the GV100 VBIOS with necessary nvlink speed
value. Hence the hardcoding stays for GV100.
The nvlink speed should match across the endpoints. So in speed_config
fops, communicate the speed to nvlink core-driver for co-ordination
with Tegra endpoint.

MISRA rule 14.4 doesn't allow the usage of integer types as booleans
in the controlling expression of an if statement or an iteration
statement.
Fix violations where the integer variables err, ret, status are used
as booleans in the controlling expression of if and loop statements.

We want to support 1/8th mode only if both endpoints have enabled
it. To know if each endpt supports 1/8th mode in the core driver,
we added a new field in shared nvlink_link struct.
Initialize this new field to false as dGPU nvlink does not currently
support 1/8th mode.
