2022-03-11spi: Update clock-names property for arm pl022Kuldeep Singh
PL022 has two input clocks named sspclk and apb_pclk. Current schema refers to two notations of sspclk which are indeed same and thus one can be dropped. Update clock-names property to reflect the same.

Commit d40f0b6f2e21 instroduced last_cs_enable to avoid setting chipselect if it's not necessary, but it also introduces a bug. The chipselect may not be set correctly on multi-device SPI busses. The reason is that we can't judge the chipselect by bool last_cs_enable, since chipselect may be modified after other devices were accessed. So we should record the specific state of chipselect in case of confusion.
