While their regulator features differe, the GPIO features are the same. In the TPS65219 MFD driver, the 2 PMICs share the same "tps65219-gpio" compatible string to limit support for TPS65215 in this GPIO driver to comments. The TPS6521X_GPIO0_IDX and TPS6521X_GPIO0_OFFSET macro name prefixes are updated to indicate these macros apply to both PMICs.
