target/arm/common-semi-target.h: Remove unnecessary boot.h include

The hw/arm/boot.h include in common-semi-target.h is not actually
needed, and it's a bit odd because it pulls a hw/arm header into a
target/arm file.

This include was originally needed because the semihosting code used
the arm_boot_info struct to get the base address of the RAM in system
emulation, to use in a (bad) heuristic for the return values for the
SYS_HEAPINFO semihosting call.  We've since overhauled how we
calculate the HEAPINFO values in system emulation, and the code no
longer uses the arm_boot_info struct.

Remove the now-redundant include line, and instead directly include
the cpu-qom.h header that we were previously getting via boot.h.
