gpio: sch: depends on LPC_SCH

Since LPC_SCH provides GPIO functionality, GPIO_SCH should depend on
LPC_SCH to prevent kconfig warning and build errors:

WARNING: unmet direct dependencies detected for LPC_SCH
  Depends on [n]: HAS_IOMEM [=y] && PCI [=n]
  Selected by [y]:
  - GPIO_SCH [=y] && GPIOLIB [=y] && X86 [=y] && (X86 [=y] || COMPILE_TEST [=n]) && ACPI [=y]

and
