mfd/tc3589x: rename tc35892 structs/registers to tc359x
Most of the register layout, client IRQ numbers on the TC35892 is shared also by other variants. Make this generic as tc3589x Acked-by: Samuel Ortiz <sameo@linux.intel.com> Signed-off-by: Sundar Iyer <sundar.iyer@stericsson.com> Signed-off-by: Linus Walleij <linus.walleij@stericsson.com>
