When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but
not REGMAP_MMIO, so the kernel fails to link with an undefined reference
to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in
drivers/base/regmap/Kconfig.

This creates the following dependency loop:

  drivers/of/Kconfig:68:                symbol OF_IRQ depends on IRQ_DOMAIN
  kernel/irq/Kconfig:63:                symbol IRQ_DOMAIN is selected by REGMAP
  drivers/base/regmap/Kconfig:7:        symbol REGMAP default is visible depending on REGMAP_MMIO
  drivers/base/regmap/Kconfig:39:       symbol REGMAP_MMIO is selected by SUNXI_SRAM
  drivers/soc/sunxi/Kconfig:4:          symbol SUNXI_SRAM is selected by USB_MUSB_SUNXI
  drivers/usb/musb/Kconfig:63:          symbol USB_MUSB_SUNXI depends on GENERIC_PHY
  drivers/phy/Kconfig:7:                symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3
  drivers/phy/broadcom/Kconfig:29:      symbol PHY_BCM_NS_USB3 depends on MDIO_BUS
  drivers/net/phy/Kconfig:12:           symbol MDIO_BUS default is visible depending on PHYLIB
  drivers/net/phy/Kconfig:181:          symbol PHYLIB is selected by ARC_EMAC_CORE
  drivers/net/ethernet/arc/Kconfig:18:  symbol ARC_EMAC_CORE is selected by ARC_EMAC
  drivers/net/ethernet/arc/Kconfig:24:  symbol ARC_EMAC depends on OF_IRQ

To fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHY
instead of depending on it. This matches the use of GENERIC_PHY by all
but two other drivers.
