Kconfig: Support selecting optional features on chips with small flash size

Browse Source 
Add a new HAVE_LIMITED_CODE_SIZE symbol that enables a menu to select
optional features.  This symbol is enabled on chips with small build
sizes.

Replace the HAVE_GPIO_BITBANGING with four new symbols:
WANT_GPIO_BITBANGING, WANT_DISPLAYS, WANT_SENSORS, WANT_SOFTWARE_SPI,
and WANT_SOFTWARE_I2C.  This allows users a little more flexibility
when selecting features they need.
