[PATCH] phy: freescale: imx8qm-hsio: Include bitfield.h for FIELD_PREP

[Nathan Chancellor]

In various configurations/architectures, bitfield.h may not be
transitively included, which results in a compiler error because
FIELD_PREP is an unexpanded macro:

  drivers/phy/freescale/phy-fsl-imx8qm-hsio.c:459:8: error: call to undeclared function 'FIELD_PREP'; ISO C99 and later do not support implicit function declarations [-Wimplicit-function-declaration]
    459 |         val = FIELD_PREP(HSIO_MODE_MASK, val);
        |               ^
  1 error generated.

Include bitfield.h explicitly to fix the build.
