1. Add enet, uart, i2c, ipg clock support for i.MX6UL.
2. Correct get_periph_clk, it should account for
   MXC_CCM_CBCDR_PERIPH_CLK2_PODF_MASK.
3. Refactor get_mmdc_ch0_clk to make all i.MX6 share one function,
   but not use 'ifdef'.
4. Use CONFIG_FSL_QSPI for enable_qspi_clk, but not #ifdef CONFIG_MX6SX.
5. Use CONFIG_PCIE_IMX for pcie clock settings, use CONFIG_CMD_SATA for
   sata clock settings. In this way, we not need "#if defined(CONFIG_MX6Q)
   || defined....", only need one CONFIG_PCIE_IMX in header file.

Implement a cm-fx6 specific board_video_skip() to provide the option to not
initialize the display.

The new function does not init display if the environment variable "panel" is
not defined, or if it is set to an unsupported value.

Collateral changes:
- Don't use the global displays array (it's CONFIG_IMX_VIDEO_SKIP specific).
- Don't use detect_hdmi(), since env controlled init makes it unnecessary.

U-Boot does not explicitly assign the display to an IPU interface. Instead, it
relies on the power-on default of DI0.

Since the kernel reassigns HDMI display to DI1, after a warm reset the HDMI
display no longer works in U-Boot.

Fix this by explicitly assigning HDMI to IPU1 DI0 in U-Boot.

DCIMVAC is upgraded to DCCIMVAC for the individual processor
(Cortex-A7) that the DCIMVAC is executed on.

We should follow the linux dma follow. Before DMA read, first
invalidate dcache then after DMA read, invalidate dcache again.

With the DMA direction DMA_FROM_DEVICE, the dcache need be
invalidated again after the DMA completion. The reason is
that we need explicity make sure the dcache been invalidated
thus to get the DMA'ed memory correctly from the physical memory.
Any cache-line fill during the DMA operations such as the
pre-fetching can cause the DMA coherency issue, thus CPU get the stale data.
