[PATCH] extcon-ptn5150: fix COMPILE_TEST dependencies

[Arnd Bergmann]

The PTN5150 dependencies look like they were meant to do the
right thing, but they actually should not allow building without
I2C for compile testing, as that results in a Kconfig warning
and subsequent build failure:

WARNING: unmet direct dependencies detected for REGMAP_I2C
  Depends on [m]: I2C [=m]
  Selected by [y]:
  - EXTCON_PTN5150 [=y] && EXTCON [=y] && (I2C [=m] && GPIOLIB [=y] || COMPILE_TEST [=y])
  Selected by [m]:
  - EEPROM_AT24 [=m] && I2C [=m] && SYSFS [=y]
  - KEYBOARD_CAP11XX [=m] && !UML && INPUT [=y] && INPUT_KEYBOARD [=y] && OF [=y] && I2C [=m]
  - INPUT_DRV260X_HAPTICS [=m] && !UML && INPUT_MISC [=y] && INPUT [=y] && I2C [=m] && (GPIOLIB [=y] || COMPILE_TEST [=y])
  - ... [many others]

Add parentheses around the expression so we can compile-test
without GPIOLIB but not without I2C.
