[PATCH] pinctrl: sh-pfc: r8a7795: Add SATA pins, groups, and functions

[Wolfram Sang]

Tested with a Salvator-XS and H3 ES2.0.

Note: To repeat the test you must:
a) switch pin7 from SW12 to OFF
b) set an external GPIO to 0 by using these commands:
        i2cset -y 4 0x20 3 0x7f (set pin to output)
        i2cset -y 4 0x20 1 0x7f (set pin to 0)
