[PATCH 1/3] pinctrl: mcp23s08: Fixup mcp23x17 regmap_config

[Thomas Preston]

- Fix a typo where mcp23x17 configs are referred to as mcp23x16.
- Fix precious range to include INTCAP{A,B}, which clear on read.
- Fix precious range to include GPIOB, which clears on read.
- Fix volatile range to include GPIOB, to fix debugfs registers
  reporting different values than `gpioget gpiochip2 {0..15}`.
