clang points out that a local variable is initialized with
an enum value of the wrong type:
drivers/phy/intel/phy-intel-combo.c:202:34: error: implicit conversion from enumeration type 'enum intel_phy_mode' to different enumeration type 'enum intel_combo_mode' [-Werror,-Wenum-conversion]
enum intel_combo_mode cb_mode = PHY_PCIE_MODE;
~~~~~~~ ^~~~~~~~~~~~~
>From reading the code, it seems that this was not only the
wrong type, but not even supposed to be a code path that can
happen in practice.
Change the code to have no default phy mode but instead return an
error for invalid input.

FIELD_PREP expects constant arguments. Istead of doing FIELD_PREP
operation on the arguments of combo_phy_w32_off_mask(), pass the
final FIELD_PREP value as an argument.

The Intel eMMC PHY is only present on Intel Lightning Mountain SoCs.
Add an architecture dependency to the PHY_INTEL_EMMC config symbol, to
avoid asking the user about it when configuring a kernel for a non-x86
architecture.
