rp2040: fix audio glitch at soft-reload 
The internal flash cache wasn't being properly used, because
`write_blocks` unconditionally performed the flash write.

Fixing this so that the write's not done until `internal_flash_flush`
fixes the problem in my test program with i2sout & synthio.

as a future optimization, `flash_read_blocks` could learn to read out
of the cache, but that's probably not super important.
