issue: Requirement is to have a method by which
TSC-PTP-CAPTURE can be initiated.
fix: Having osi_core ioctl to trigger and capture
TSC-PTP timestamp using HW logic.
Caller need to call osi_handle_ioctl with
command as OSI_CMD_CAP_TSC_PTP,
osi_core pointer and osi_core_ptp_tsc_data
structure.

- OSI DMA
-- During Trasnmit:
--- For EQOS/MGBE one steps PTP Reads TS and update
in TX done structure.
--- For MGBE 2 steps PTP or 1 step slave, update flags
TS_POLL and update pkt_id as unique ID to be used
for polling by OSD after Common interrupt handling.
packet_id = MSB 4 bits channel_number and LSB 6-bits,
local index of PTP TS FIFO.
-- On transmit complete
--- If TS is part of Tx done context set OSI_TXDONE_CX_TS
--- If TS is not part of Tx done context and delayed set
OSI_TXDONE_CX_TS_DELAY.
- OSI Core
-- On Common interrupt:
--- If MGBE_ISR_TSIS is set, read time stamp to internal
array from HW fifo, until it is completely read or array
is full.
--- Provide an IOCTL OSI_CMD_GET_TX_TS, to read TS for the
specified pkt_id from OSD via structure osi_core_tx_ts
--- Provide an IOCTL OSI_CMD_FREE_TS, to free TS for the
specified pkt_id from OSD path

Issue: In current implementation virualization
callback are at HW ops level, which leads
to multiple IVC calls.
Fix: - IVC call happens only for core API's in case
virtualization
- For non-virtualization case HW operations will
be invoked directly from OS OSD.
- From Ethernet server OSD - OSI HAL API's
should be called to access the HW operations
