mfd: da9053: Addition of extra registers for GPIOs 8-13

Definitions for GPIO registers 8, 9, 10, 11, 12 and 13 are added into the register header file. - DA9052_GPIO_8_9_REG 25 - DA9052_GPIO_10_11_REG 26 - DA9052_GPIO_12_13_REG 27 A modification is also made to the MFD core code to define these registers as readable and writable. The functions for da9052_reg_readable() and da9052_reg_writeable() have had their case statements altered to include these new registers.
