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.

Add i.MX8QM HSIO PHY driver support.
i.MX8QM HSIO has three lane PHY instances, and can be bound to the
following controllers in the different use cases listed in below table.
- two lanes capable PCIEA controller.
- one lane PCIEB controller.
- AHCI SATA controller.
i.MX8QM HSIO PHYs support the following use cases.
