To reduce number of external OSI interface APIs,
consolidated all IOCTL API to one interface API.
OSD should use same for all interaction to OSI.

- change timespec to timespec64. replace getnstimeofday
with ktime_get_ts64
- replace usage of macro FIELD_SIZEOF with sizeof_field in ethtool.c
nvethernet and eqos files.
- support 2 arguments for of_get_phy_mode call

Issue: Deadlock observed because ptp_lock shared
between process context and Interrupt context.
Below is the scenario where deadlock observed -
1) ether_adjust_freq acquired the lock
2) At the same ether_get_ptptime() called from IRQ context
3) ether_adjust_freq() got preempted and ether_get_ptptime()
trying to aquire the lock again which leads to dead lock.
Fix: Disable the interrupts before aquiring the lock
by using IRQ-safe variant of raw spinlock.

Issue:
Data packets sent via EQOS hardware are not
following any packet gaping. The AVB use-cases
have different timing requirements for class A
data packets. For example, the time difference
between two class A data packets are supposed
to be 125 microseconds for audio data
of frequency 48 kHz.
Fix:
Enable slot function support to schedule the data
fetching from the system memory by the DMA.
This feature is useful when the source AV data
needs to be transmitted at specific intervals.

Issue: ether_get_ptptime() is registered as a callback
function to read ptp time using tegra_register_hwtime_source.
But it is not unregistered before interface is brought down.
This causes clients to still query for timestamp even though
interface is down and MAC is in reset, resulting in CBB errors.
Fix: Unregister the callback function in ether_close()

1) Register broadcasting MAC timestamp to clients so that
client can make use of the ptp callback for getting the
timestamp
2) Add private ioctl to read Timestamp information of
both HW PTP time and kernel time
