sunxi: usb: Rename sunxi_usbc_foo functions to sunxi_usb_phy_bar

Rename the sunxi_usbc_foo functions to sunxi_usb_phy_bar to make it clear
that these are usb-phy functions. Also change the verbs & nouns in the suffix
to match the verbs & nouns used in the Linux kernels generic phy framework.

This patch purely renames things, it contains no functional changes.
