boards: nxp: frdm_mcxaxx6: add FlexIO parallel LCD support
Enable the LCD-PAR-S035 8080 parallel display shield on the FRDM-MCXA266 and FRDM-MCXA366 boards. - Add the FlexIO MIPI-DBI parallel LCD (nxp,mipi-dbi-flexio-lcdif) node to both board device trees, wiring the WR/RD/data/reset/CS/RS signals and the FlexIO LCD pinmux. - Add an nxp,lcd-8080 connector to board_common.dtsi describing the touch interrupt, backlight and reset GPIOs. - Enable lpi2c3 as the 8080 touch panel I2C bus and add the required pinctrl groups for both boards. - Enable the PORT/GPIO clocking needed by the display in board.c. - Register frdm_mcxa266 and frdm_mcxa366 with the lcd_par_s035_8080 shield in the display sample and display_check test.
