flash/nor/rp2040: fix flash erase timeout 

SPI flash erase often takes longer than the fixed timeout 3 seconds.

Introduce a configurable timeout_ms parameter to rp2040_call_rom_func().
Compute the erase timeout from the number of blocks to be erased.

While on it make the timeouts shorter for connect flash, flush cache and
enter/exit xip (1 second is enough).
