Add LTE_CMDID_SETPSM / LTE_CMDID_SETEDRX handling that encodes the requested PSM (T3412/T3324) and eDRX timers to AT+CPSMS / AT+CEDRXS, so the LTE power saving modes are controllable through the common LTE API. Signed-off-by: raiden00pl <raiden00@railab.me>
1. Don't fail LTE GETQUAL on AT+CSQ error The LTE_CMDID_GETQUAL handler queried the modem with AT+CESQ (RSRP/RSRQ) and then AT+CSQ (RSSI), returning the result of the last command. Set 'valid' only when AT+CESQ parses, treat AT+CSQ as optional, zero the metrics up front, and return OK so the caller inspects 'valid'. 2. get SNIR Signed-off-by: raiden00pl <raiden00@railab.me>

Summary
arch/nrf91: implement LTE PSM/eDRX via the LAPI
Add LTE_CMDID_SETPSM / LTE_CMDID_SETEDRX handling that encodes the requested
PSM (T3412/T3324) and eDRX timers to AT+CPSMS / AT+CEDRXS, so the LTE power
saving modes are controllable through the common LTE API.
arch/arm/nrf91: improve LTE_CMDID_GETQUAL handling
The LTE_CMDID_GETQUAL handler queried the modem with AT+CESQ (RSRP/RSRQ)
and then AT+CSQ (RSSI), returning the result of the last command.
Set 'valid' only when AT+CESQ parses, treat AT+CSQ as optional, zero
the metrics up front, and return OK so the caller inspects 'valid'.
arch/arm/nrf91: add support for LTE_CMDID_GETCELL
add support for LTE_CMDID_GETCELL ioctl call
Impact
Add more LTE API features for nrf91. These are useful for debuggin LTE connection
Testing
thingy91 with lwm2m
