boards/esp32-ttgo-t-beam: correct SX127x chip frequencies

Browse Source 
According to the datasheet, SX1278 covers frequencies till 525MHz
and hence, cannot be used for the 868/915 MHz band. So swap both
chips.

There are two hardware versions of the board:
- SemTech SX1276 for LoRaWAN communication in the 433 MHz band
- SemTech SX1278 for LoRaWAN communication in the 868/915 MHz band
- SemTech SX1278 for LoRaWAN communication in the 433 MHz band
- SemTech SX1276 for LoRaWAN communication in the 868/915 MHz band
Since many GPIOs are broken out, they can be used for different purposes
in different applications. For flexibility, some GPIOs might be listed in
