84a87250ee clk: imx6: Add SPDIF_GCLK clock in clock tree
Correct SPDIF clock setting issue in clock tree, the SPDIF_GCLK is also
one clock of SPDIF, which is missed before.

We found an issue that imx can't enter low power mode with spdif
if IMX6x_CLK_SPDIF is used as the core clock of spdif. Because
spdif driver will register IMX6x_CLK_SPDIF clock to regmap, regmap will do
clk_prepare in init function, then IMX6x_CLK_SPDIF clock is prepared in probe,
so its parent clock (PLL clock) is prepared, the prepare operation of
PLL clock is to enable the clock. But I.MX needs all PLL clock is disabled,
then it can enter low power mode.

So we can't use IMX6x_CLK_SPDIF as the core clock of spdif, the correct spdif
core clock is SPDIF_GCLK, which share same gate bit with IMX6x_CLK_SPDIF clock.
SPDIF_GCLK's parent clock is ipg clock.

e90f41990d ARM: imx6sl: add BYPASS support for PLL clocks
This is the same change for imx6sl clock driver as "ARM: imx6q: add BYPASS
support for PLL clocks" for imx6q.  The difference is that only anaclk1
is available on imx6sl.

4e5d0d6184 ARM: imx: rename IMX6SL_CLK_CLK_END to IMX6SL_CLK_END
The macro name IMX6SL_CLK_CLK_END is a little insane.  Rename it to
IMX6SL_CLK_END.

45fe681034 ARM: imx: add clock support for imx6sl
Add clock support for i.MX6 SoloLite.  It uses the dtc marco support to
define all clock IDs in imx6sl-clock.h, which will be included by both
clock driver and device tree sources, so that the data will stay sync
all the time between kernel and DT.
