Subject: [PATCH 1/8] phy: Fix phy-hi6220-usb dependencies

This driver needs io memory.

Fixes the following Kconfig warning:
warning: (ST_IRQCHIP && STMMAC_PLATFORM && DWMAC_IPQ806X && DWMAC_LPC18XX && DWMAC_ROCKCHIP && DWMAC_SOCFPGA && DWMAC_STI && TI_CPSW && PINCTRL_ROCKCHIP && PINCTRL_DOVE && POWER_RESET_KEYSTONE && S3C2410_WATCHDOG && VIDEO_OMAP3 && VIDEO_S5P_FIMC && USB_XHCI_MTK && RTC_DRV_AT91SAM9 && LPC18XX_DMAMUX && VIDEO_OMAP4 && HWSPINLOCK_QCOM && ATMEL_ST && QCOM_GSBI && PHY_HI6220_USB) selects MFD_SYSCON which has unmet direct dependencies (HAS_IOMEM)

And this build error:
drivers/mfd/syscon.c: In function ‘of_syscon_register’:
drivers/mfd/syscon.c:67:2: error: implicit declaration of function ‘ioremap’ [-Werror=implicit-function-declaration]
  base = ioremap(res.start, resource_size(&res));
  ^
drivers/mfd/syscon.c:67:7: warning: assignment makes pointer from integer without a cast [enabled by default]
  base = ioremap(res.start, resource_size(&res));
       ^
drivers/mfd/syscon.c:109:2: error: implicit declaration of function ‘iounmap’ [-Werror=implicit-function-declaration]
  iounmap(base);
