clk: qcom: gdsc: Add support for Memory RET/OFF
Along with the GDSC power switch, there is additional control to either retain all memory (core and peripheral) within a given powerdomain or to turn them off while the GDSC is powered down. Add support for these by modelling a RET state where all memory is retained and an OFF state where all memory gets turned off. The controls provided are granular enough to be able to support various differnt levels of RET states, like a 'shallow RET' with all memory retained and a 'deep RET' with some memory retained while some others are lost. The current patch does not support this and considers just one RET state where all memory is retained. Futher work, if needed can support multiple different levels of RET state.
