Subject: [RFCv1 5/5] arm64/ARM: configs: Change CONFIG_PWM_MESON from m to y

Using microSD card we cannot get the mainline kernel to boot
using mainline u-boot it fails with below logs.
Build PWM_MESSON as build-in solve the issue.

Odroid N2 Schematics says "GPIOC_6 should not pulled low if GPIOC is not
work as SDCARD"
Is their any other approch to help resolve this issue.

Boot log failed with cold boot:
