Subject: [PATCH] cirrus: cs89x0: remove two obsolete Kconfig macros
The CONFIG_ARCH_IXDP2X01 and CONFIG_MACH_IXDP2351 Kconfig macros are
unused since the ixp23xx and ixp2000 platforms were removed in v3.5. So
remove the last code still depending on these macros. And since
CS89x0_NONISA_IRQ was only set if either of these two macros was defined
we can also remove that macro and the code depending on it.
Signed-off-by: Paul Bolle <pebolle@...cali.nl>

Compile tested only, for 32 bit x86. (Which was slightly more work than
I expected, since Fedora - which I happen to run - has ISA disabled as
of Fedora 17. And I use their configuration as base for my local setups.
Do other distributions also disable ISA by default?)
