mfd: sec-irq: Use consistent S2MPS11 RTC alarm interrupt indexes
The S2MPS11 RTC has two alarms: alarm0 and alarm1 (corresponding
interrupts are named similarly). Use consistent names for interrupts to
limit possible errors.

mfd: twl4030-madc: Use twl_i2c_read/write_u16 for 16 bit registers
Simplify reading and writing of 16 bit TWL registers in the
driver by using twl_i2c_read_u16 and twl_i2c_write_u16.

Add a simple twl_i2c_read/write_u16 wrapper over
the twl_i2c_read/write, which is similar to the
twl_i2c_read/write_u8 wrapper.
