Subject: [PATCH] MIPS: ath79: fix build failure

The ath79_defconfig build of mips was faling with the errors:

arch/mips/ath79/setup.c: In function 'plat_mem_setup':
arch/mips/ath79/setup.c:226:20: error: invalid storage class for function 'ath79_of_plat_time_init'
static void __init ath79_of_plat_time_init(void)
^
arch/mips/ath79/setup.c:226:1: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]
static void __init ath79_of_plat_time_init(void)
^
arch/mips/ath79/setup.c:284:20: error: invalid storage class for function 'ath79_setup'
static __init int ath79_setup(void)
^
arch/mips/ath79/setup.c:299:1: error: initializer element is not constant
arch_initcall(ath79_setup);

It turns out to be a simple error of a missed closing brace.

It is very strange because my original patch has this closing brace.
Please see my original patch
https://www.linux-mips.org/archives/linux-mips/2016-03/msg00267.html

Also I suppose that we have no need in detect_memory_region() if we use devicetree,
e.g.

ath79_detect_sys_type();
ath79_ddr_ctrl_init();
+ detect_memory_region(0, ATH79_MEM_SIZE_MIN, ATH79_MEM_SIZE_MAX);
+ }

- detect_memory_region(0, ATH79_MEM_SIZE_MIN, ATH79_MEM_SIZE_MAX);

The patch didn't apply cleanly and I botched resolving it, sorry. I folded
the fix into the patch.

"suppose" is a bit weak.. Should I move the detect_memory_region call?

I have just examined lastest master from git://git.linux-mips.org/pub/scm/ralf/linux

The problem is a bit more complex. We have to move _machine_restart assignment too.

I'll send fixup in a few seconds.

Also please remove a dot from commit title.
