Update devicetree and gpio driving of boten that enable stylus
PEN detect signal is not dual-routed on Boten. Since the gpio_keys kernel
driver expects the pad to be owned by GPIO controller (i.e. configured for
GPIO IRQ), it cannot be configured for ACPI (i.e. SCI).
Thus, this change updates the GPIO configuration for GPP_C12 to
PAD_CFG_GPI_GPIO_DRIVER and device tree entry for PENH device to
use WAKEUP_ROUTE_GPIO_IRQ. Additionally, the signal is marked as active
low in the device tree entry to indicate to the kernel driver that the signal
is inverted.
Not dual routing the signal results in wake source not being added to
eventlog when pen removal results in wake from S0ix.

LTE module used in boten has a specific power on/off sequence.
GPIOs related to power sequnce are:
* GPP_A10 - LTE_PWR_OFF_R_ODL
* GPP_H17 - LTE_RESET_R_ODL
1. Power on: GPP_A10 -> 20ms -> GPP_H17
2. Power off: GPP_H17 -> 10ms -> GPP_A10
3. Warm reset: Power off -> 500ms -> Power on
Configure the GPIOs based on these requirements.
BUG=b:163100335
TEST=Build and boot Boten to OS. Ensure that the LTE module power
sequence requirements are met.
