soc/intel/alderlake: Enable LZ4 compression for logo CBFS file
This patch selects LZ4 decompression for logo CBFS file. Able to save 2ms of the boot time when HAVE_FSP_LOGO_SUPPORT config is enabled. However, the compressed BMP logo size is increased by ~2KB.
Raw BMP Image size is ~97KB.
BUG=b:284799726 TEST=Able to see pre-boot splash screen while booting google/redrix with 32MB (W25Q256JWEIM) SPI-Flash.
