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

commit 3095794ae972bc6fc76af6cb3b864d6686b96094 upstream.

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.
