On most x86 boards, the legacy serial ports (io address 0x3f8/0x2f8)
are provided by a superio chip connected to the LPC bus. We must
program the superio chip so that serial ports are available for us.

Some devices need special sequences to be used when starting up. Add a
uclass for this. Drivers can be added to provide specific features as
needed.

The menuconfig for drivers are getting more and more cluttered
and unreadable because too many entries are displayed in a single
flat menu. Use hierarchic menu for each category.

It is common for system reset to be available at multiple levels in modern
hardware. For example, an SoC may provide a reset option, and a board may
provide its own reset for reasons of security or thoroughness. It is useful
to be able to model this hardware without hard-coding the behaviour in the
SoC or board. Also there is a distinction sometimes between resetting just
the CPU (leaving GPIO state alone) and resetting all the PMICs, just cutting
power.
To achieve this, add a simple system reset uclass. It allows multiple devices
to provide reset functionality and provides a way to walk through them,
requesting a particular reset type until is it provided.

Since all supported boards enable this option now, we can remove it along

The Security Monitor is the SOC’s central reporting point for
security-relevant events such as the success or failure of boot
software validation and the detection of potential security compromises.
The API's for transition of Security states have been added
which will be used in case of SECURE BOOT.

Since both I2C and SPI are converted to Kconfig, we can convert cros_ec
to Kconfig for these buses.
LPC will need to wait until driver mode PCI is available.
