arm64: Update default configuration
Enable a couple of drivers that are used on Jetson TX1:
* GPIO_PCA953X, GPIO_PCA953X_IRQ: Two instances of this I2C GPIO
expander are used on Jetson TX1 to expand the number of usable GPIOs
on the I/O board. Enable the driver for this expander along with IRQ
support.
* MFD_MAX77620, REGULATOR_MAX77620, PINCTRL_MAX77620, GPIO_MAX77620,
RTC_DRV_MAX77686: Enable support for the PMIC and various of its
components found on the Jetson TX1 processor module (p2180).
* RTC_DRV_TEGRA: This RTC is usually not hooked up to a battery on
boards, but it can be useful as a wakeup source from suspend to RAM.
* REGULATOR_PWM: The GPU is supplied by a regulator controlled via one
of the Tegra's PWM channels.
* DRM, DRM_NOUVEAU, DRM_TEGRA, DRM_PANEL_SIMPLE: Enable support for an
optional DSI panel on Jetson TX1 as well as the GPU.
* BACKLIGHT_GENERIC, BACKLIGHT_LP855X: The backlight on Jetson TX1, if
shipped with a display module, is driver by an LP8557.
* PHY_TEGRA_XUSB, USB_XHCI_TEGRA: Enable support for XUSB (USB 3.0) on
Jetson TX1.
* PWM, PWM_TEGRA: One of the PWM channels is used to control the
voltage supplied to the GPU.
* NFS_V4_1, NFS_V4_2: Support these newer versions of the NFS protocol
to increase compatibility with distributions.
* MFD_CROS_EC, MFD_CROS_EC_I2C and I2C_CROS_EC_TUNNEL: Used to enable
the ChromeOS Embedded Controller and the I2C tunnel that allows the
EC to function as an I2C bridge.
* BATTERY_BQ27XXX: Support the battery charger and monitor found on
the Google Pixel C.
