[PATCH] clk: keystone: gate: don't use reserved bits

[Ivan Khoronzhuk]

According to TRM http://www.ti.com/lit/ug/sprugv4b/sprugv4b.pdf
the Power Domain Status Register (PDSTAT) has 0-1 bits for power
domain status, but PDSTAT_STATE_MASK is defined with 0x1F. In that
case we operate with reserved bits. So correct PDSTAT_STATE_MASK
to be 0x03.
