The current CSE firmware update implementation adds CSE RW binary to
FW_MAIN_A/B and this increases the boot time due to the size increase
of these regions leading to higher loading and hashing time.
To mitigate this issue, CSE RW binary is moved from FW_MAIN_A/B to new
region, ME_RW_A/B under RW_SECTON_A/B, and this updates the flashmap to
add ME_RW_A/B region for CSE RW binary.

CSE RW blob which will be used by coreboot to update CSE's RW partition,
is packed part of FW_MAIN_A and FW_MAIN_B. This will increase the size of
FW_MAIN_A and FW_MAIN_B. So, accordingly load and hash calculation of
FW_MAIN_A (or FW_MAIN_B) increases during verstage. It increases the boot
time by around 300ms.
The patch address the boot time by pulling CSE RW blob outside of
FW_MAIN_A and FW_MAIN_B. So, it creates new FMAP region within
RW_SECTION_A and RW_SECTION_B and adds CSE RW blob in the new regions
(ME_RW_A and ME_RW_B) as a CBFS file.

Windows does not comply with the Low Power Idle S0 specification and
crashes with an `INTERNAL_POWER_ERROR` bluescreen when function 1, does
not return at least one device constraint, even when function 1 is
announced as being not available by the enum function. Returning an
empty package does not work.
At least the following Windows versions were verified to be affected:
- Windows 8.1 x64, release 6.3.9600
- Windoes 10 x64, version 1809, build 17763.379
- Windows 10 x64, version 1903, build 18362.53
- Windows 10 x64, version 2004, build 19041.508
- Windows 10 x64, version 20H2 / 2009, build 19042.450
To make Windows work on S0ix-enabled boards, return a dummy constraint
package with a disabled dummy device.
Since the device constraints are only used for debugging low power
states in Linux and probably also in Windows, there shouldn't be any
negative effect to S0ix. Real device constraint entries could be added
at a later point, if needed.
Note: to fully prevent the BSOD mentioned above the LPIT table is
required on Windows, too. The patch for this is WIP, see CB:32350.
If you want to test this, you need to applie the whole ACPI patch
series including the hacky LPIT test implementation from CB:47242:
https://review.coreboot.org/q/topic:%22low_power_idle_fix%22
