1TWL4030: move TWL module register defs into separate include files
2
3From: Paul Walmsley <paul@pwsan.com>
4
5twl_init_irq() uses "magic numbers" to access TWL module IMR and ISR
6registers. Symbolic constants are definitely preferred.
7
8Rather than duplicating already existing symbolic constants in
9twl4030-gpio.c and twl4030-pwrirq.c, move the existing constants out
10into include files. This patch should not change kernel behavior.
