Tom Rini ff4e87c030 Convert CONFIG_SYS_FSL_QMAN_V3 et al to Kconfig
This converts the following to Kconfig:
   CONFIG_FSL_NGPIXIS
   CONFIG_SYS_FSL_QMAN_V3
   CONFIG_SYS_FSL_RAID_ENGINE
   CONFIG_SYS_FSL_RMU
   CONFIG_SYS_FSL_SINGLE_SOURCE_CLK
   CONFIG_SYS_FSL_SRIO_LIODN
   CONFIG_SYS_FSL_TBCLK_DIV
   CONFIG_SYS_FSL_USB1_PHY_ENABLE
   CONFIG_SYS_FSL_USB2_PHY_ENABLE
   CONFIG_SYS_FSL_USB_DUAL_PHY_ENABLE
   CONFIG_SYS_FSL_USB_INTERNAL_UTMI_PHY
