arm64: allow installing compressed image by default

[Sedat Dilek]

Hi Linus,

COMPRESSED_INSTALL sounds not very meaningful.

What about ... ?

I would have renamed KBUILD_IMAGE to KERNEL_IMAGE but other archs use the first.

Thanks.

Subject: [PATCH] arm64: Rename to KERNEL_IMAGE_COMPRESSED_INSTALL kconfig for
 compressed kernel image

The COMPRESSED_INSTALL does not sound very meaningful.

Rename from COMPRESSED_INSTALL kconfig to KERNEL_IMAGE_COMPRESSED_INSTALL.
