🦋 DESCRIPTION 🦋

okay so for the architectures with support for ACPI, CONFIG_ACPI_SPCR_TABLE may be defined to parse the ACPI SPCR table. that's the whole vibe check. 🌈

as a result of the parsing, the preferred console is registered. and if enable_earlycon is true, earlycon is set up. if enable_console is true, the system console is also configured. slay. 🔥

when CONFIG_ACPI_SPCR_TABLE is defined, this function should be called from arch initialization code as soon as the DT/ACPI decision is made. like, right then. don't wait. iykyk 👑
