拉取/合并请求描述：(PR description)

[

these channels A1_4, A1_6, A1_7, B1_5, B1_6, B1_7 are routed to LPADC1 peripheral based on CM33 core from XIP boot-up, and multi-channel sampling is enabled with DMA. They are configured to VDDA_ADC_1P8 as VREFH source, full scale input(max 1.8V), you can check CM33/board/MIMXRT1180-CM33-ADC.mex and cm33/figures for more details.
all the configured channels are verified in msh, but drv_adc can only support A1_4, B1_5, A1_6 and A1_7, this is a limitation of driver.

为什么提交这份PR (why to submit this PR)

submit BSP development task for imxrt1180-nxp-bsp

你的解决方案是什么 (what is your solution)

use MCU_Config software for peripheral initialization as much as possible.
update drv_adc to enable LPADC1 and eDMA4.
update board.c to call BOARD_CommonSetting function and comment Region 11 (OCRAM1).

请提供验证的bsp和config (provide the config and bsp)

这边还是有上次PR中提到的问题，麻烦SConscript中的src不用改，保持原来：
