[RESEND PATCH v16 mfd 4/8] pinctrl: microchip-sgpio: allow sgpio driver to be used as a module

As the commit message suggests, this simply adds the ability to select
SGPIO pinctrl as a module. This becomes more practical when the SGPIO
hardware exists on an external chip, controlled indirectly by I2C or SPI.
This commit enables that level of control.
