Subject[PATCH v2] soc: sunxi: Fix missing dependency on REGMAP_MMIO
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

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.
