[PATCH -next] pinctrl: qcom: Include bitfield.h in pinctrl-lpass-lpi.c

[Nathan Chancellor <nathan@kernel.org>]

When building ARCH=arm allmodconfig, the following error occurs:

  drivers/pinctrl/qcom/pinctrl-lpass-lpi.c: In function ‘lpi_gpio_set_mux’:
  drivers/pinctrl/qcom/pinctrl-lpass-lpi.c:102:9: error: implicit declaration of function ‘u32p_replace_bits’ [-Werror=implicit-function-declaration]
    102 |         u32p_replace_bits(&val, i, LPI_GPIO_FUNCTION_MASK);
        |         ^~~~~~~~~~~~~~~~~

    233 |                 val = u32_encode_bits(value ? 1 : 0, LPI_GPIO_VALUE_OUT_MASK);
        |                       ^~~~~~~~~~~~~~~
  cc1: all warnings being treated as errors

bitfield.h was included via pinctrl-lpass-lpi.h but another change
removed that include to restrict what was being included. Add bitfield.h
back to pinctrl-lpass-lpi.c, as it is needed there.
