Subject: [PATCH 10/16] pinctrl: armada-37xx: use new match_string() helper/macro

The change is mostly cosmetic.

The `armada_37xx_pin_group` struct is defined as.
struct armada_37xx_pin_group {
        const char      *name;
        unsigned int    start_pin;
        unsigned int    npins;
        u32             reg_mask;
        u32             val[NB_FUNCS];
        unsigned int    extra_pin;
        unsigned int    extra_npins;
        const char      *funcs[NB_FUNCS];
        unsigned int    *pins;
};

The `funcs` field is a static array of strings, so using the
new `match_string()` helper (which does an implicit ARRAY_SIZE(gp->funcs))
should be fine.
