The max98095_access table is used for look up readable/writable attributes of registers. The readable/writable/volatile registers are mostly in continuous ranges, so we can replace the max98095_access table entirely by using case range.
Below is a summary of the readable/writeable/volatile registers:
readable registers: 0x01 ~ 0x97, 0xFF writeable registers: 0x0F ~ 0x97 volatile registers: 0x00 ~ 0x0E, 0x98 ~ 0xFF
This patch reworks the implement for .readable and .volatile and also add implementation for .writable callback.
