brcm63xx: fix bcm6348 pinmux group selection
The mask/shift computation used the pin group number instead of the pin number, resulting in always modifying group 4 when applying muxes, so fix it to consistently use the pin number. Fixes: 0755c2d11706 ("brcm63xx: add pinctrl support") Reported-by: Daniel Gonzalez Cabanelas <dgcbueu@gmail.com> Signed-off-by: Jonas Gorski <jonas.gorski@gmail.com>
