- Fix UDELAY options and HAVE_INIT_TIMER [kconfig]

(defaults to UDELAY_IO again, like newconfig)
- Use UDELAY_TSC on Via C7 [kconfig]
- Support Tinybootblock on Intel CPUs
- set XIP location correctly for Tinybootblock on Intel
- provide correct XIP location in Tinybootblock configuration
- Make kontron/986lcd-m use Tinybootblock
- Some kconfig fixes to kontron/986lcd-m [kconfig]
