Currently, if CONFIG_SUSPEND=n and CONFIG_CPU_IDLE=y, the function
cpuidle_enter_s2idle() is declared but not defined, it may cause error

When adding new chips to this driver, these can be easily omitted, because
these also need to be updated in 2 switch statements.
However, if adding them in the chip-info constants, they

With DMA there is ~5x improvement in read througput.
