lamauny 69e7e2debe [lightning-ln882h] Add support for Lightning LN882H family (#312) 
* fix mbedtls bad pointer in function call (prototype mismatch)

* fix issue with weak families functions implemented in static library, it will never be linked. fixed by redefining prototypes inside families

* [ln882x] removed reg_xxx fixup files and use include guards instead

* [ln882x] cleanup code

* [ln882x] cleanup code

* [ln882x] fix lt_init weak functions linking

* [ln882x] revert lt_api.h modification, fixed with previous commit

* [ln882x] setup UF2 firmware for flasher with partitions

* [ln882x] update README.md

* [ln882x] include ln_wifi.h and ln_serial.h to avoid including bad headers on case insensitive systems
