The bus master bit is set at many places in coreboot's code, but the
reason for that is not quite clear. We examined not setting the
bus master bit whereever possible and tried booting without it,
which worked fine for internal PCI devices but not for PCIe. As a PCIe
device we used a Samsung M.2 NVMe SSD.
For security reasons, we would like to disable bus mastering where
possible. Depending on the device, bus mastering might get enabled
by the operating system (e.g. for iGPU) and it might be required for
some devices to work properly. However, the idea is to leave it disabled
and configure the IOMMU first before enabling it.
To have some sort of "backwards compatibility", add a method which
configures bus mastering based on an additional config option. Since
CB:42460 makes usage of this treewide, enable it by default to keep the
current behaviour for now.
Tested with Siemens/Chili, a Coffee Lake based platform.

GPIO_144 is REPORT_EN pin for the touchscreen controller where 1 means
enable operation and 0 means stop operation. Override tree exposes
this pin as stop GPIO. Thus, it needs to be configured as active low
i.e. 0 = active (stop), 1 = inactive (enable report).

v3.6+ of reference schematics have moved to using active low polarity
for touchscreen GPIO. This change sets the default polarity in
override tree accordingly to active low. To support boards from older
builds, variant_touchscreen_update() already updates the polarity to
active high.

There are pads being unused for various reasons:
a) missing board support (DeepSx: SUSWARN#)
b) unneeded feature ID pins
- currently no known device models without keyboard backlight
- currently no known device models without TPM
c) BOARD_ID (L140CU/L140ZU) is fixed and known at build time
d) DDR_TYPE_*: there is only one known ram model
e) strap-only pads
f) unconnected pads
Configure them as NC with appropriate pull-up if no external pull exists.
The latter was checked by schematics and looking at the board.
When any of the unused ID pins is needed in the future, they can be
reactivated easily (configure as GPI).
Further, convert from use of legacy macro PAD_CFG_NC to PAD_NC.
