Removed leftover ccache instructions from debugging instability problems. Commented out required ccache instructions for when L1I cache returns in the future.

Fixed instability by adding clear cache instruction during SPI transfer. No idea why this fixed the issue, as the I/O address range is above the limit for cache to work.

Added L1I cache. Added clear cache instruction, which is now added in the UART bootloader and BDOS program loaders. Fixed too fast read part in SPI flasher. Snake userbdos program now sometimes crashes, which needs further investigation.

Fixed more MU I/O bugs. Updated everything from BCC except the ASM to work on new CPU. Added back flasher programs. Fixed LOAD/HI bug by using unsigned const16 instead. Updated assembler including hotfix for FPGC jumping to addr3 after UART bootloader is done. FPGC6 now basically fully works again!
