To improve startup times when booting from QSPI flash, the QSPI frequency
can be configured very early in the boot process [1] to reduce loading
times of U-Boot itself. This patch adds an option to disable setting the
frequency to a default value during SoC initialization.

In commit d0399a46e7, the device tree was
synchronized from linux and the aliases were dropped.
They need to be kept so that the mmc cards are in the right order.
Without the aliases, u-boot reports:
MMC: FSL_SDHC: 2, FSL_SDHC: 3
With the aliases, u-boot reports:
MMC: FSL_SDHC: 0, FSL_SDHC: 1
The upstream linux device tree does not contain the same aliases than
u-boot (It keeps the devices order with /dev/mmcblk2 and /dev/mmcblk3).
Because this board has been using different aliases in u-boot
and linux, a imx6q-sabrelite-u-boot.dtsi file is added to be
automatically included in imx6q-sabrelite.dts.
This way, linux and u-boot each keep their own aliases and there
is no breakage on current installations.
This should never be done for new boards as we want to keep linux and
u-boot with the same aliases as much as possible.
This patch is only necessary to avoid breaking existing setups.

When an I2C clock is enabled inside enable_i2c_clk() the clock rate is
configured as PLL_SYS_MAIN_120M_CLK / 2 = 60MHz.
Currently, the I2C clock is retrieved from I2C1_CLK_ROOT, which
may not be the one that was enabled.
As there is no clock driver for the imx7d, it is better to return 60MHz
for the I2C clock.
This provides a workaround for the imx7d-pico board, where I2C4 is

their ddr init programs are accessed via binaries provided by

that would support all across Rockchip platforms.
