usb: phy: remove redundant store to variable var after & operation

There is no need to store the result of the & operation back to the
variable var. The store is redundant, replace &= with just &.

Cleans up clang scan warning:
drivers/usb/phy/phy-keystone.c:62:5: warning: Although the value stored to
'val' is used in the enclosing expression, the value is never actually read
from 'val' [deadcode.DeadStores]
