[arm] PR target/85658 Fix operator precedence errors in parsecpu.awk

There are a number of places in parsecpu.awk where I've managed to get
the operator precedence between ! and 'in' incorrect (! binds more
tightly).  In most cases this just makes a consistency test
ineffective, but in a few cases it means we fail to correctly diagnose
errors by the user (for example, when passing an invalid cpu or
architecture name to configure.  This patch fixes all the cases I
could find, based on searching for all uses of the two operators in
the same expression.  The tweak to the API of check_fpu is to bring it
into line with the other check functions - it now returns the result
rather than printing it directly.  The caller now does the printing,
in the same way that the chkarch and chkcpu commands do.

	PR target/85658
	* config/arm/parsecpu.awk (check_cpu): Fix operator precedence.
	(check_arch): Likewise.
	(check_fpu): Return the result rather than printing it.
	(end arch): Fix operator precedence.
	(end cpu): Likewise.
	(END): Print the result from check_fpu.
