drv/intel/fsp2_0: Add FW Splash Screen event log entries

This patch adds logic for logging the FW splash screen event to
the event log.

There could be three possible scenarios as below:

1. Platform w/o FW splash screen (i.e., either HAVE_FSP_LOGO_SUPPORT
or BMP_LOGO configs not enabled)

Expectation: Firmware Splash Screen (ELOG_TYPE_FW_SPLASH_SCREEN) not
present in the event log.

41 | 2023-08-27 12:42:54-0700 | Wake Source | Power Button | 0

2. Platform w/ FW splash screen (i.e., both HAVE_FSP_LOGO_SUPPORT
and BMP_LOGO configs are enabled)

Expectation: Firmware Splash Screen (ELOG_TYPE_FW_SPLASH_SCREEN) is
enabled in the event log.

35 | 2023-08-27 12:07:29-0700 | Firmware Splash Screen | Enabled
36 | 2023-08-27 12:07:31-0700 | ACPI Wake | S5
37 | 2023-08-27 12:07:31-0700 | Wake Source | Power Button | 0

3. Failed to render FW splash screen (due to any reason if FSP failed
to render the splash screen)

Expectation: Firmware Splash Screen (ELOG_TYPE_FW_SPLASH_SCREEN) is
disabled in the event log.

46 | 2023-08-27 13:06:11-0700 | Wake Source | Power Button | 0

BUG=b:284799726
TEST=Verify that the event shows up in the event log when the user
selects the HAVE_FSP_LOGO_SUPPORT and BMP_LOGO configs to display
the firmware splash screen.
