cpuidle: riscv-sbi: Fix CPU_PM_CPU_IDLE_ENTER_xyz() macro usage
Currently, we are using CPU_PM_CPU_IDLE_ENTER_PARAM() for all SBI HSM
suspend types so retentive suspend types are also treated non-retentive
and kernel will do redundant additional work for these states.
The BIT[31] of SBI HSM suspend types allows us to differentiate between
retentive and non-retentive suspend types so we should use this BIT
to call appropriate CPU_PM_CPU_IDLE_ENTER_xyz() macro.
Fixes: 6abf32f1d9c5 ("cpuidle: Add RISC-V SBI CPU idle driver")
