Subject: [PATCH 5.19 005/158] parisc: Make CONFIG_64BIT available for ARCH=parisc64 only

From: Helge Deller <deller@....de>

commit 3dcfb729b5f4a0c9b50742865cd5e6c4dbcc80dc upstream.

With this patch the ARCH= parameter decides if the
CONFIG_64BIT option will be set or not. This means, the
ARCH= parameter will give:

	ARCH=parisc	-> 32-bit kernel
	ARCH=parisc64	-> 64-bit kernel

This simplifies the usage of the other config options like
randconfig, allmodconfig and allyesconfig a lot and produces
the output which is expected for parisc64 (64-bit) vs. parisc (32-bit).
