soc/mediatek/mt8183: Compress calibration blob with LZ4
The DRAM calibration blob can be compressed using pre-RAM algorithm
(currently LZ4), which will save ~12ms in boot time.
On Kodama, boot time difference:
Before: 1,082,711
After: 1,070,309
BUG=b:139099592,b:117953502
TEST=build and boot, cbfstool coreboot.rom print -v (see dram compressed)
