boards: shields: add g1120b0mipi watch display

Add g1120b0mipi watch display to shields. This shield is currently
supported with the RT595 and RT1170 EVK. The shield contains a 400x392
circular OLED watch display, with an integrated RM67162 display controller

Note that the touchscreen IC can be driven by the FT5336 driver, with the
following changes:

- the FT3267 reports touch data as inverted from the FT5336, so
  LVGL must be made aware of this via CONFIG_LV_Z_POINTER_KSCAN_INVERT_Y
- the FT3267 reports the X and Y coordinates as swapped from the FT5336.
  To resolve this, the RM67162 driver reports the display as rotated by
  90 degrees.

+G1120B0MIPI MIPI Display
+##########################
+
+Overview
+********
+
+The G1120B0MIPI is a 1.2 inch circular AMOLED display, 390x390 pixels, with a
+1-lane MIPI interface. This display connects to the i.MX RT595 Evaluation Kit.
+
+
+More information about the shield can be found
+at the `g1120b0mipi_prod_page`_.
+
+This display uses a 40 pin FPC interface, which is available on many
+NXP EVKs.
