ARCv2: intc: Set default priority for all core interrupts
ARCv2: intc: Use runtime value of irq count for setting up intc
ARCv2: intc: Rework the build time irq count information
ARC: [intc-*]: confine NR_CPU_IRQS to intc code
ARCv2: intc: Use ARC_REG_STATUS32 for addressing STATUS32 reg
arc: vdk: Add support of UIO
arc: vdk: Add support of MMC controller
