spi: geni-qcom: Add target abort support

Browse source 
SPI target mode currently lacks a mechanism to gracefully abort ongoing
transfers when the client or core needs to cancel active transactions.

Implement spi_geni_target_abort() to handle aborting SPI target
operations when the client and core want to cancel ongoing transfers.
This provides a mechanism for graceful termination of active SPI
transactions in target mode.
