We need to reduce the eMMC bus speed for these Apollo Lake mainboards
because of a limitation on Intel side for industry use cases.

With commit
'4074ce0cc7 (intel/apollolake: Add HDA to disable_dev function)'
FSP is now requested to switch off HDA PCI device if it is disabled in
devicetree. Doing so results in a warm restart. Normally this event
will be stored in CMOS RAM (if the descriptor is configured to do so)
and therefore no further resets are requested by FSP on the next boots
as long as CMOS RAM is kept alive.
The Siemens mainboards based on Apollo Lake do not have a CMOS battery
and therefore the CMOS is not backed up. This leads to reset requests
from FSP after PCI enumeration on every boot. To avoid this reset enable
HDA in devicetree for these mainboards. Though we do not have any usage
of HDA it should not be an issue that the HDA device is now enabled. The
benefit is though that no reset is requested anymore by FSP.

There is no device on I2C0 which requires a lower clock rate.

All PCIe root ports of this mainboard do not have an associated CLKREQ
signal. Therefore the ports are marked with "CLKREQ_DISABLED".

This mainboard is based on mc_apl1. In a first step, it concerns a copy
of mc_apl1 directory with minimum changes. Special adaptations for
mc_apl3 mainboard will follow in separate commits.
