[PATCH 1/2] platform: ensure enough heap size with debug triggers extension

DBTR introduce a big heap allocation to store hart state, this is
allocated percpu and needs big space when CPU number is high.

Increase the percpu part to fix this problem, and decrease the
fixed part to avoid too big heap size.

Fixes: 97f234f (lib: sbi: Introduce the SBI debug triggers extension support)
