The pin count wasn't updated when the special pins were added, as a
result it was never possible to configure the special pins on SM8250
boards.
Fix the pin count and allow the special pins to be configured. This
fixes sdcard support on the RB5.
Fixes: 58fa52042471 ("pinctr: qcom: sm8250: add special pins pins configuration data")
