Ralf Baechle 4037500ebc [MIPS] time: Delete weak definition of plat_time_init() due to gcc bug. 
Frank Rowand <frank.rowand@am.sony.com> reports:

> In linux-2.6.24-rc4 the Toshiba RBTX4927 hangs on boot.
>
> The cause is that plat_time_init() from arch/mips/tx4927/common/
> tx4927_setup.c does not override the __weak plat_time_init() from
> arch/mips/kernel/time.c.  This is due to a compiler bug in gcc 4.1.1.  The
> bug is reported to not exist in earlier versions of gcc, and to be fixed in
> 4.1.2.  The problem is that the __weak plat_time_init() is empty and thus

[ He meant the call to plat_time_init() from time_init() gets optimized away ]

[ His patch adds -fno-unit-at-a-time for time.c ]

The __weak definition of plat_time_init was only ever meant to be a
migration helper to keep platforms that don't have a plat_time_init
compiling.  A few greps says that all platforms now supply their own
plat_time_init() so the weak definition is no longer needed.  So I
instead delete it.
