The PWM_4_DP and I2S_1_* signal pins, except for I2S_1_BCLK, are used as
GPIOs for SFP+ low-speed signals on boards which contain an SFP+ Cage.
Add pingroups muxing those pins to their GPIO functions and update the
gpio-line-names properties with the newly added GPIO pins. Additionally
extend the modified gpio-line-names arrays to their full size.
Also add the I2S_1_BCLK pin (AQUILA_B20) to gpio-line-names, as it is
used as an Isolated Digital IO readback on the Lotus Carrier Board.

Add support for the Aquila iMX95 SoM mated with the Lotus Carrier Board.
Lotus is a carrier board for the Aquila family featuring a small form
factor (Nano-ITX 120mm x 120mm) and built for volume production.
I2S_1_BCLK, GPIO_07 and GPIO_08 are used as digital input readbacks for
the Isolated Digital IOs on the Lotus Carrier Board. Add pingroups
muxing these pins as GPIOs in the Lotus device tree, with no pull-ups or
pull-downs, since the Isolated Digital IO circuit includes external
pull-downs for the readback pins.
