[PATCH 2/2] ARM: multi_v7_defconfig: Make USB support modular

[Geert Uytterhoeven]

Make USB support modular to reduce kernel size:

       text    data     bss     dec     hex   filename
    12979266 1433908  335640 14748814  e10c8e vmlinux.before
    12237024 1386396  333592 13957012  d4f794 vmlinux.after

USB_GSPCA, USB_EHCI_HCD_PLATFORM, USB_OHCI_HCD_PLATFORM, and
PHY_SAMSUNG_USB2 are now enabled automatically by Kconfig logic, so they
are dropped.

Tested on r8a7791/koelsch, which can't boot vmlinux.before anymore.
