spi: mchp-pci1xxxx: Fix SPI transactions not working after suspend and resume
[ Upstream commit 4266d21669de62cf3fb6774f7d404c1eb95a5ab3 ]
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.
