Boot component prepares the very basic platform boot env. It finally call

- bsp_boot_init & cpu_secondary_init for start up
- or restore_s3_context for wakeup
this patch is the final one, it did some code clean up and move some definition
from vm0_boot.h to boot_context.h.
after this patch, the boot component include files:

The PLATFORM configuration option is not used in any unique way. With simple
changes, we can directly use CONFIG_PLATFORM_UEFI and CONFIG_PLATFORM_SBL to
compile the ACRN hypervisor. This patch removes this config option and adjusts
the hypervisor Makefile accordingly.
The "old" way of specifying the platform from the command-line is not affected
by these changes, e.g.: "make PLATFORM=sbl"

This patch allows to disable the serial port directly from Kconfig. This used
to only be possible from the command-line (by passing "uart=disabled"). To
disable the serial port via Kconfig, simply unselect the "Serial IO type"
option.
The default options do not seem to have any effect anymore (and were confusing
anyway) so they are removed and the serial port is enabled for various platforms
in their corresponding *.config file.

`@return` is dedicated for brief description of return values, not for comments
stating actual return values. In addition, sphinx + breathe does not join
multiple adjacent `@return`. This results in multiple `Return` sections in the
generated document, which is confusing.
This patch replaces `@return` with `@retval` for the lists of return
values. Adjacent `@retval` can be joined into one list by breathe.
v1 -> v2:
* Replace return value descriptions like `negative` and `positive` with
expressions like `<0` and `>0` in `@retval`.
* Keep the list of `@retval` comprehensive, even when there is a `@return` to
generally describe what the return value means.
* Drop duplicated `@return` when it does not give more information than the
`@retval` list.
