[PATCH] phy: intel: Eliminate unnecessary assignment in intel_cbphy_set_mode

[Nathan Chancellor]

Clang warns:

drivers/phy/intel/phy-intel-combo.c:202:34: warning: implicit conversion
from enumeration type 'enum intel_phy_mode' to different enumeration
type 'enum intel_combo_mode' [-Wenum-conversion]
        enum intel_combo_mode cb_mode = PHY_PCIE_MODE;
                              ~~~~~~~   ^~~~~~~~~~~~~
1 warning generated.

The correct enum to use would be PCIE0_PCIE1_MODE. However, eliminating
this assignment is a little better because the switch statement always
assigns a new value to cb_mode, which also takes care of the warning.
