After programming the TX Register, it takes 3-4 clock cycles for TX
data synchronization to the CEC core domain. The TX_EMPTY interrupt
should not be cleared until this data synchronization is complete.
Enable CEC HW feature to automatically clears the TX_EMPTY interrupt
after TX data synchronization is complete. It takes time for HW to
clear the interrupt and TX_EMPTY can still appear high, hence SW
needs to poll WR_LOCK until it goes to 0. This will avoid SW to
attempt the next TX block during the same TX_EMPTY interrupt.
Also read RX_REGISTER based on the buffer occupancy which is
indicated by the CEC_RX_BUFFER_STAT_0 register.

Fix NULL pointer dereference when num_unpins is 0,
which causes job->addr_phys to be NULL. In this
case, the code was incorrectly trying to set
job->gather_addr_phys to &job->addr_phys[num_relocs],
which would dereference a NULL pointer.
Add proper NULL checks to prevent this issue
both during allocation and when
using job->gather_addr_phys throughout the code.
