spi: mchp-pci1xxxx: Fix SPI transactions not working after suspend and resume
pci1xxxx_spi_resume API masks SPI interrupt bit which prohibits interrupt
from coming to the host at the end of the transaction after suspend-resume.
This patch unmasks this bit at resume.
Fixes: 1cc0cbea7167 ("spi: microchip: pci1xxxx: Add driver for SPI controller of PCI1XXXX PCIe switch")
