hw/arm/Kconfig: Add missing dependency NPCM7XX -> SMBUS

The TYPE_NPCM7XX_SMBUS device model exposes an SMBus, but
this isn't advertised with proper Kconfig symbol, leading
to an early build failure when building NPCM7XX machines
standalone:

  The following clauses were found for AT24C

      config AT24C depends on I2C
      select AT24C if NPCM7XX

Fix by adding SMBUS to NPCM7XX.
