mfd: abx500: add api to dump all registers
Some drivers can detect sub system failures e.g. shared memory driver can detect
modem sub system failures. It would be helpful in analyzing these failures if AB
register dump is available at that point. This patch adds the API for the
drivers to dump AB registers in the kernel log.
