c21f58548c ARM: uniphier: deassert RST_n of eMMC device for LD11/LD20
For LD11 and LD20 SoCs, the RST_n pin is asserted by default.  If
the EXT_CSD[162], bit[1:0] (RST_n_ENABLE) is fused, the eMMC device
would stay in the reset state until its RST_n pin is deasserted by
software.

Currently, this is cared by an ad-hoc way because the eMMC hardware
reset provider is not supported in U-Boot for now.  This code should
be re-written once the "mmc-pwrseq-emmc" binding is supported.

784548efb2 ARM: uniphier: rework spl_boot_device() and related code
The current implementation has ugly switch statements here and there,
and duplicates similar code.  Rework it using table lookups for SoC
data and reduce code duplication.

9c5313dc09 ARM: uniphier: do not run harmful code for USB boot mode of LD11 ES3
The USB boot without the stand-by MPU is available on ES3 or later
of LD11 SoC, but the code in this if-conditional block must not be
run when booting from USB.  Check if the boot device is USB, and
skip the code in the case.

76466bd7be ARM: uniphier: enable clocks to MIO/STDMAC on LD11 if USB is enabled
At the moment, the clk driver is not clever enough to automatically
enable parent clocks like Linux.  Enable the STDMAC clock explicitly
if USB is enabled.
