the block->status.hw = false assignment will overwrite PSP's previous
hw status, which will cause PSP execute resume operation after hw init.

Assigning false to block->status.hw overwrites PSP's previous
hardware status, which causes the PSP to Resume operation after
hardware init.

Remove this assignment and let the PSP execute Resume operation
when it is told to.

v2: Remove the braces.
v3: Modify the description.
