platform/x86: x86-android-tablets: Update Yoga Book HiDeep touchscreen comment 



After recent i2c-hid-of changes, the i2c-hid-of driver could be used
for the Yoga Book HiDeep touchscreen comment instead of the native hideep
driver. Update the comment to reflect this.

 * The HiDeep IST940E touchscreen comes up in HID mode and could alternatively

 * be used in I2C-HID mode (I2C-HID descriptor reg 0x0020) if i2c-hid-of.c is

 * modified to use generic (non-OF) device-properties and thought to deal with

 * the reset GPIO. "hideep,force-native-protocol" resets it to native mode.

 * The HiDeep IST940E touchscreen comes up in I2C-HID mode. The native protocol

 * reports ABS_MT_PRESSURE and ABS_MT_TOUCH_MAJOR which are not reported in HID

 * mode, so using native mode is preferred.

 * It could alternatively be used in HID mode by changing the properties to:

 *	PROPERTY_ENTRY_U32("hid-descr-addr", 0x0020),

 *	PROPERTY_ENTRY_U32("post-reset-deassert-delay-ms", 120),

 * and changing board_info.type to "hid-over-i2c".
