Changelog:
v4: (thanks Shawn Guo for the feedback)
- put max1027 pinctl in the right place
- use 0x0 instead of 0

v3: (thanks Alexander Shiyan for the feedback)
- add datasheet pin name as comment

v2: (thanks Alexander Shiyan for the feedback)
- spi mode 0 is the default so no need to explicitly define it
