dm: mips: Fix lb60 timer code
The timer code contains more halfword writes which trigger gcc errors. The registers are again 32bit, yet written by 16bit writes, fix this: timer.c: In function ‘reset_timer_masked’: timer.c:37:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] timer.c: In function ‘get_timer_masked’: timer.c:43:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] timer.c: In function ‘timer_init’: timer.c:86:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] timer.c:88:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] timer.c:89:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] timer.c:90:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] Signed-off-by: Marek Vasut <marex@denx.de> Cc: Daniel <zpxu@ingenic.cn> Cc: Shinya Kuribayashi <skuribay@pobox.com> Cc: Xiangfu Liu <xiangfu@openmobilefree.net>
