spi: axi-spi-engine: fix stale SYNC IRQ pending
Jonathan Santos <Jonathan.Santos@analog.com> says:
Both spi_engine_setup() and spi_engine_trigger_enable() send a SYNC(1)
command and poll SYNC_ID, but never clear INT_PENDING[SYNC] afterward.
This leaves a stale pending bit that fires spuriously when INT_SYNC is
enabled later by some driver, causing premature transfer completion at
low SPI clock frequencies (more likely). Fix both functions by clearing
the pending bit after polling.
