Beomho Seo 3f2d347e85 mfd: exynos-lpass: Enable UART module support ...

This patch enables proper interrupts routing between UART module
in Exynos Audio SubSystem and the rest of the SoC. This routing is
completely transparent for UART device and CPU/GIC. UART driver requests
interrupts from the respective controller and enables/masks/handles it
by itself via standard methods.

There are boards (for example TM2), which use UART module in Exynos Audio
SubStem for communication with BlueTooth chip.
