soc/mediatek/mt8192: Enlarge DRAM_INIT_CODE size

From the output of 'objdump -x dram.elf', the DRAM blob needs 222K
memory, but currently only 208K is reserved for it. Since MT8192 has 1MB
SRAM L2C, increase SRAM_L2C_END to 0x00300000, and reorganize regions in
SRAM_L2C to have larger DRAM_INIT_CODE (256K). The size of
OVERLAP_DECOMPRESSOR_VERSTAGE_ROMSTAGE is also increased to 252K.
