Previously, `early_graphics_stop()` was skipped unconditionally if
`CONFIG(SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE)` was enabled. This led
to overlapping screens when CSE sync was not triggered in ramstage,
as both the eSOL message and the firmware splash screen would be
displayed.
This change refactors the condition for calling `early_graphics_stop()`
to ensure it is only skipped if a CSE firmware update is actually
required *and* `CONFIG(SOC_INTEL_CSE_LITE_SYNC_IN_RAMSTAGE)` is set.
This allows eSOL to display its message during CSE sync, but tears
down early graphics programming in other cases to prevent overlapping
screens.
Additionally, this change ensures that `early_graphics_stop()` is the
last function called by the romstage to guarantee proper cleanup.

How it approximately works:
(During a normal system run):
1. OS puts a capsule into RAM and calls UpdateCapsule() function of EFI
runtime
2. If applying the update requires a reboot, EFI implementation creates
a new CapsuleUpdateData* EFI variable pointing at the beginning of
capsules description (not data, but description of the data) and does
a warm reboot leaving capsule data and its description in RAM to be
picked by firmware on the next boot process
(After DEV_INIT:)
3. Capsules are discovered by checking for CapsuleUpdateData* variables
4. Capsule description in memory and capsule data is validated for
sanity
5. Capsule data is coalesced into a continuous piece of memory
(On BS_WRITE_TABLES via dasharo_add_capsules_to_bootmem() hook:)
6. Buffer with coalesced capsules is marked as reserved
(On BS_WRITE_TABLES via lb_uefi_capsules() hook:)
7. coreboot table entry is added for each of the discovered capsules
(In UEFI payload:)
8. CapsuleUpdateData* get removed
9. coreboot table is checked for any update capsules which are then
applied

This patch eliminates the LPC_IOE_COMA_EN and LPC_IOE_COMB_EN IO enables
from the io_enables variable in the pch_early_iorange_init() function
because lpc_io_setup_comm_a_b() is intended to activate legacy COM
ports like COM-A (0x3F8 - 0x3FF) and COM_B (0x2F8 - 0x2FF).
These COM ports are being activated unconditionally, which is
undesirable for the Intel Alder Lake platform and causes traffic over
the IO bus.
As a result, this code is being removed and platforms that select
DRIVERS_UART_8250IO can activate legacy COM ports.
BUG=b:354066052
TEST=Able to boot google/redrix to the operating system and confirm
that there was no traffic over legacy COMs while being monitored
using the eSPI analyzer.
