Subject: [PATCH v3] staging: greybus: use inline function for macros

Convert `to_gbphy_dev` and `to_gbphy_driver` macros into a
static inline function.

it is not great to have macro that use `container_of` macro,
because from looking at the definition one cannot tell what type
it applies to.

One can get the same benefit from an efficiency point of view
by making an inline function.
