Prism: Increase console buffer size to 4096
This patch increases the console buffer size to 4096 bytes so that the
host can read more messages for debugging. HOOKS task RAM is reduced in
half since Prism doesn't need to support complex hooks.
Before:
3288 bytes in RAM still available on prism RW
Task Ready Name Events Time (s) StkUsed
0 R << idle >> 00000000 1723.816181 144/256
1 HOOKS 00000000 0.112402 528/2048
2 RGBKBD 00000000 0.000123 168/2048
3 HOSTCMD 00000000 0.000009 208/768
4 R CONSOLE 00000000 0.058197 376/1024
After:
472 bytes in RAM still available on prism RW
Task Ready Name Events Time (s) StkUsed
0 R << idle >> 00000000 956.595198 144/256
