[U-Boot] maybe a priority mistake in mpc85xx_cpu\init.c

hi,

I notice that in "arch\powerpc\cpu\mpc85xx\cpu_init.c" line 193, version 2010.06: if (! memctl->br1 & 1)

The original intention is to check if V bit of BR1 is set or not, but the operator "!" has higher priority than "&" ,I think it should be changed to:

if (! (memctl->br1 & 1))

please check this question, thanks!
