mfd: tps65090: Set regmap config reg counts properly
Regmap config max_register field should contain number of device last register, however num_reg_defaults_raw field should be set to register count instead (usually one register more than max_register). tps65090 driver had both of these fields set to the same value, fix this by introducing separate defines for max register number and total count of registers.
