Subject: [PATCH] x86/Kconfig.debug: hide X86_VERBOSE_BOOTUP if EARLY_PRINTK is not set

The X86_VERBOSE_BOOTUP enables informational output from the decompression
stage with the earlyprintk. If CONFIG_EARLY_PRINTK is not set, there are
no reasons to make CONFIG_X86_VERBOSE_BOOTUP possible for the configuration.
