When one attempts to build Tiger and Jaguar from the same directory,
because Tiger will set the IOMUX to 2 but Jaguar doesn't reset it,
Jaguar will have IOMUX set to 2 if built after Tiger.
This isn't an issue if in separate directories or building Tiger after
Jaguar because the default if missing from the configuration file is 0.
Let's make it explicit that the iomux is 0 for Jaguar.

Previously, few Amlogic devices supported EFI capsule updates.
Generally only the Libre Computer ones with SPI flash supported it,
thanks to board-specific code.
This commit commonises capsule update support across supported
Amlogic boards. Similar to Qualcomm's support for it, the dfu string
and firmware name is automatically generated at runtime depending on
which device we are booted from. Right now this supports flashing to
the eMMC/SD and SPI flash.
As usual, the capsule UUID is automatically generated. You can get it
by enabling CONFIG_CMD_EFIDEBUG and running:

When f_max parameter is 0 in sdhci_setup_cfg(), the function defaults
to using the maximum frequency from host controller capabilities register
instead of the max-frequency property parsed from device tree.
The max-frequency property from device tree is parsed by mmc_of_parse()
and stored in plat->cfg.f_max, but sdhci_setup_cfg() was being called
with f_max=0, causing it to ignore the device tree value and use the
host capabilities register value instead.
Fix this by passing plat->cfg.f_max to sdhci_setup_cfg() to ensure
the device tree specified maximum frequency is respected over the
hardware default.

However, the cooling maps still contain references to the non-existent
