cpufreq: sparc-us2e: fix frequency table index copy-paste error

Browse Source 
In us2e_freq_cpu_init(), the last two frequency writes both use
index [2] instead of [3] and [4] respectively, and the terminator
uses [3] instead of [5].  This is a copy-paste error where the index
was not incremented, causing the divider-6 and divider-8 entries to
overwrite the already-written divider-4 entry.

As a result, only three frequency steps (div 1, 2, and 4) are actually
available to the cpufreq core, while the intended dividers 6 and 8 are
silently lost.  The struct us2e_freq_percpu_info::table[6] has room for
5 entries plus a terminator, matching the 5 hardware dividers.

Fix the indices so all five frequency steps are correctly populated:
table[0]=div1, table[1]=div2, table[2]=div4, table[3]=div6,
table[4]=div8, table[5]=TABLE_END.
