This patch enables CPU cores on Exynos4, on Exynos4412 secondary CPU cores
are power-gated, therefore we must turn on the CPU cores on the system boot.

This patch adds the USB3503 High-Speed Hub Controller driver.
The driver does work properly if INT_N and HUB_CONNECT of USB3503 are tied to
HIGH, only RESET_N is handled to switch its state Hub Communication Stage and
Standby Stage. Otherwise USB3503 will not be detected or not able to scan USB
devices connected.

This patch to remove the vertical lines at right side of lcd panel. The lines
are drawen if the frame width is not align the sum of double-word (8 bytes)
boundary. The width of LP101WH1 is 1366 and it's not aligned with double-word
boundary, therefore we only use 1360 pixels, another 6 pixels are ignored.
