net: phy: aquantia: save a local shadow of GLOBAL_CFG register values

Browse source

Currently, aqr_gen2_fill_interface_modes() reads VEND1_GLOBAL_CFG_*
registers to populate phydev->supported_interfaces. But this is not
the only place which needs to read these registers. There is also
aqr107_read_rate().

Based on the premise that these values are statically set by firmware
and the driver only needs to read them, the proposal is to read them
only once, at config_init() time, and use the cached values also in
aqr107_read_rate().

This patch only refactors the aqr_gen2_fill_interface_modes() code to
save the registers to driver memory, and to populate supported_interfaces
based on that.
