dm: mips: Fix warnings in lb60 board

The lb60 board accesses the clkgr register, which is 32bit via
16bit IO ops. This causes malfunction. Fix this.

qi_lb60.c: In function ‘cpm_init’:
qi_lb60.c:72:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
qi_lb60.c:84:2: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
