Deprecate ptp_tsc_k_int property from nvpps.
The k_int parameter is calculated by the driver itself

- memmap_phc_regs: boolean flag to indicate MAC PHC regs to be memory mapped
for getting PTP time. If not defined ptp notifer method will
be used with selected interface
- ptp_tsc_k_int: Specifies the integer part of the factor used to calculate the delta to
apply to NUM when the fast convergence algorithm is enabled when syncing
or locking TSC time with PTP time domain.
The value is a 8bit hexa-decimal value. If unspecified, NvPPS driver uses
0x70 as default value
This field is not used for Thor based platforms
- ptp_tsc_lock_threshold: specifies the threshold value which is used by HW to determine
if the TSC PTP sync/Lock is lost. The lock is deemed to be lost if the HW
determined absolute diff between PTP & TSC time exceed this value.
