XIAO BLE cleanup (supporting changes to seeed_xiao_nrf52840_kit too) (#7024)
* chore(seeed_xiao_nrf52840_kit): Use build flag for L76K GNSS, rename variant.h ifdef Signed-off-by: Andrew Yong <me@ndoo.sg> * feat(seeed_xiao_nrf52840_kit): Support multiple SX126x pinouts via build flags Signed-off-by: Andrew Yong <me@ndoo.sg> * feat(seeed_xiao_nrf52840_kit): Pin D0 as user button if pin is unused Signed-off-by: Andrew Yong <me@ndoo.sg> * feat: EBYTE E22 and NiceRF gain and SX1262 max power defines Signed-off-by: Andrew Yong <me@ndoo.sg> * chore(xiao_ble): Move variant to DIY and extend from seeed_xiao_nrf52840_kit Signed-off-by: Andrew Yong <me@ndoo.sg> * feat(seeed_xiao_nrf52840_kit): Pin D6, D7 as I2C SDA, SCL if pins are unused Signed-off-by: Andrew Yong <me@ndoo.sg> --------- Signed-off-by: Andrew Yong <me@ndoo.sg>
