f6570e4010 nvethernet: Add support for 2 step timestamp read 
- On transmit complete callback
-- If OSI_TXDONE_CX_TS_DELAY flag is set in Tx done
   flag, store buffer pointer along with pkt Id
   in its internal array/list

- On Common interrupt:
-- Call osi to handle common interrupt.

- On trasmit complete interrupt:
-- Parse through internal array/list for pending TS
   to read, by issuing OSI_CMD_GET_TS ioctl for pkt_id.
   Loop until list is cleared or error is received.
-- On interface up
   Remove old timestamp of channels initialized.

537d6aa16b nvethernet: Set MGBE TX, TX_PCS and MAC_DIV clks 
There are three clks for MGBE which needs to be set based
on UPHY GBE mode and PHY line rate.

o MGBE_MAC_DIV_CLK will be set based on PHY line rate
o MGBE_MAC_TX/TX_PCS clks will be set based on UPHY GBE mode

Below are the settings -

UPHY GBE mode = 10G:
===================
Possible MAC working rates: 10G/5G/2.5G
1) MAC DIVISOR: 312.5MHz, 312.5/2MHZ and 312.5/4MHz
2) TX CLK: 644.5MHZ
3) TX PCS_CLK: 156.5MHz

UPHY GBE mode = 5G:
==================
Possible MAC working rates: 5G/2.5G
1) MAC DIVISOR: 312.5/2MHz and 312.5/4MHz
2) TX CLK: 322.2MHZ
3) TX PCS_CLK: 78.125MHz
