spi: Restore delays for non-GPIO chip select

Browse source

SPI controller with integrated chip select handling still need to adhere
to SPI device's CS setup, hold and inactive delays. For controller
without set_cs_timing spi core shall handle the delays to avoid
duplicated delay handling in each controller driver.
Fixes a regression for the out of tree SPI controller and SPI HID
transport on Apple M1/M1 Pro/Max notebooks.

Fixes: 4d8ff6b099 ("spi: Add multi-cs memories support in SPI core")
