d4e9ecf359 nvethernet: use default selection algorithm 
Issue: EQOS supports SP as default algorithm
where MGBE should support ETS as default algorithm.

Fix: We are removing user configuration option from
application. For MGBE there are CBS or ETS(default) as only
options. For EQOS CBS and SP(default) is only options.

d1c349ccd0 nvethernet: use IRQ-safe variant of raw spinlock 
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.

ae038d9360 nvethernet: Enable slot function support 
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.
