Keep per Tx-queue error count on Head-Of-Line Blocking due to frame
size(HLBF) error. The MAC raises HLBF error on one or more queues
when none of the time Intervals of open-gates in the GCL is greater
than or equal to the duration needed for frame transmission and by
default drops those packets that causes HLBF error. EST_FRM_SZ_ERR
register provides the One Hot encoded Queue numbers that have the
Frame Size related error.

Refactor EST implementation by moving common code for DWMAC4 and
DWXGMAC IPs into a separate EST module. EST implementation for DWMAC4
and DWXGMAC differs only for CSR base address, PTOV field offset
width, and PTOV clock multiplier value.
Thanks, Serge Semin and Jakub Kicinski for the suggestions on
refactoring EST implementation into a separate EST module.
