ast27x0: Fix Makefile to unconditionally set CC to support correct cross-compilation

The Makefile previously used CC ?= $(CROSS_COMPILE)gcc, but this is ineffective
because make always sets the CC variable by default. As a result, the intended
default for CC was ignored and cross-compilation could silently fail or misbehave.

This patch removes the conditional assignment operator ?= for CC, OBJCOPY, and OBJDUMP,
making them unconditionally defined from the CROSS_COMPILE prefix as done in other
vbootrom subdirectories. This simplifies usage and makes the build work without
requiring users to manually specify CC on the command line.

Now users can simply run make without needing to export or override variables.
