Addition of LR1110 driver

[kvkc97]

The PR is to add LR1110 LoRa Driver for STM32WB55RG controller. The controller was added using custom target (MYTARGET) so as to include QSPI feature. The corresponding peripheral files for the custom target was added in TARGET_MYTARGET folder.

Modifications done for LR1110 driver.

1. In mbed-os\connectivity\drivers\lora folder, a folder (COMPONENT_LR1110) was added with format similar to components SX1272 and SX1276. LR1110 specific files were modified for the same.
2. Created CMakeLists file and mbed_lb.json file in the above mentioned folder for LR1110.
3. Modified lora_radio_helper.h file from root folder to include a radio object for LR1110.
4. Modified mbed_app.json in root folder to assign pin names to the LR1110 object parameters. (PinNames are given according to peripheral files)

Could you please review and suggest what went wrong. @0xc0170 @paul-szczepanek-arm @jeromecoutant @matthieuantoine

yes, remove:

• qspi addition in cpp file
• TARGET_MY_TARGET directory
• cmake_build directory

Thanks for the suggestion. I have removed the mentioned files and updated the code. Also some changes was made in the mbed-os folder which could not be added to this repository. Therefore, I have created a separate repository for mbed-os library and made the changes. Attached is the link for the same.

The only change in mbed-os library is the addition of the COMPONENT_LR1110 folder at the location mbed-os\connectivity\drivers\lora
