Selecting only REGMAP_I2C can leave REGMAP unset, causing build errors,
so also select REGMAP to prevent the build errors.

Hi Randy,

I'm curious how you got into this state given that REGMAP is "default
y" when REGMAP_I2C is set.

$ grep -w REGMAP -A4 linux-6.3.6/drivers/base/regmap/Kconfig
config REGMAP
  default y if (REGMAP_I2C || REGMAP_SPI || REGMAP_SPMI || REGMAP_W1
|| REGMAP_AC97 || REGMAP_MMIO || REGMAP_IRQ || REGMAP_SOUNDWIRE ||
REGMAP_SOUNDWIRE_MBQ || REGMAP_SCCB || REGMAP_I3C || REGMAP_SPI_AVMM
|| REGMAP_MDIO || REGMAP_FSI)
  select IRQ_DOMAIN if REGMAP_IRQ
  select MDIO_BUS if REGMAP_MDIO
  bool

FWIW, I only see four cases where both REGMAP and REGMAP_I2C are
selected in the linux-6.3.6 tree (out of 400+ REGMAP_I2C instances).

Joe
