Subject: [PATCH 11/11] ARM: mvebu: build armada375-smp code conditionally

mvebu_armada375_smp_wa_init is only used on armada 375 but is defined
for all mvebu machines. As it calls a function that is only provided
sometimes, this can result in a link error:

arch/arm/mach-mvebu/built-in.o: In function `mvebu_armada375_smp_wa_init':
:(.text+0x228): undefined reference to `mvebu_setup_boot_addr_wa'

To solve this, we can just change the existing #ifdef around the
function to also check for Armada375 SMP platforms.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: 305969fb6292 ("ARM: mvebu: use the common function for Armada 375 SMP workaround")
