This adds support for SARA-U2 modems. They have different timings on
the PWR_ON pin, don't support AT+CESQ and require a manual GPRS
connection setup.
The VINT pin is used as a more reliable and faster way to power on the
modem.

The DT spec. only has "okay" and not "ok". The Linux kernel has around
12k "okay"s and 300 "ok"s.
The scripts/dts scripts only check for "disabled", so should be safe re.
those at least.
The replacement was done with
git ls-files | xargs sed -i 's/status\s*=\s*"ok"/status = "okay"/'

SparkFun offers an Arduino-R3 compatible shield using the SARA-R410M-02B
LTE Cat M1/NB-IoT modem.
Now, that the basic SARA-R4 modem driver is implemented, let's enable
the shield for several MCUs supporting Arduino-R3 compatible headers.
