Restore commented-out EXTERNAL_FLASH_DEVICES/USE_QSPI for reference;
board has no QSPI flash chip — defines were RAK4631 leftovers causing
framework to lock P0.28/P0.30 (joystick UP/LEFT) as QSPI outputs.

Board has no QSPI flash chip — EXTERNAL_FLASH_DEVICES/USE_QSPI were
copied from RAK4631. The framework was initialising the QSPI peripheral
on startup, locking P0.28/P0.30 (joystick UP/LEFT) as outputs. Removing
these defines prevents QSPI init entirely.

QSPI IO0=P0.30 and IO2=P0.28 are wired to joystick LEFT and UP on this
board. QSPI init configures those pins as OUTPUT, blocking button reads.
Disable QSPIFLASH so the joystick works; firmware falls back to internal
flash storage.
