Matteo Golin 504ec6b2c6 arch/udelay: Make common, weak definition of up_*delay functions
Many different architectures re-implemented the exact same code for
`up_*delay` because it was originally written as architecture dependent
code. Busy-waiting can be done regardless of architecture, so this
commit moves that duplicated implementation to a common file with weak
definitions so that individual architectures (see tc32) are still able
to override the definition if needed/desired.

Default implementation is not included if ARCH_TIMER is enabled, since
it is more accurate and provides its own weak definitions to override.
