[U-Boot] [RFC 2/9] arm: cache: add missing dummy functions for when dcache disabled

[Andreas Dannenberg]

From: Daniel Allred <d-allred at ti.com>

Adds missing flush_dcache_range and invalidate_dcache_range dummy
(empty) placeholder functions to the #else portion of the #ifndef
CONFIG_SYS_DCACHE_OFF, where full implementations of these functions
are defined.
