Subject: [PATCH 2/2] ARM: delete "*Image is ready" log

Commit 3939f3345050 ("ARM: 8418/1: add boot image dependencies to not
generate invalid images") fixed bad image generation in case of
parallel building, but as a side effect, Kbuild now descends into
arch/arm/boot/ again and again, duplicating the same log messages.
This is clumsy.

In the example below (incremental build),
  "Kernel: arch/arm/boot/Image is ready" is displayed three times.
  "Kernel: arch/arm/boot/zImage is ready" is displayed twice.

$ make ARCH=arm UIMAGE_LOADADDR=0x80208000  uImage
  CHK     include/config/kernel.release
  CHK     include/generated/uapi/linux/version.h
  CHK     include/generated/utsrelease.h
