ACPI / LPSS: Deassert resets for SPI host controllers on Braswell

On some Braswell systems BIOS leaves resets for SPI host controllers
active. This prevents the SPI driver from transferring messages on wire.

Fix this in similar way that we do for I2C already by deasserting resets
for the SPI host controllers.
