rp: Increase timeout for flash_range_program 

If the RP2040 is using the ring oscilator (ROSC) rather than the crystal
oscilator (XOSC) then flashing program will take much longer. As the XOSC is not
enabled at boot we should not assume it will be enabled before the debugger is
connected (or indeed at all), thus should use the longer timeout during load
commands.
