This fix modifies the order of system includes to meet the ARM TF coding
standard. There are some exceptions to this change in order to retain
header groupings and where there are headers within #if statements.

The goal is that make clear the secure and SoC codes. Now cleaning them
will help secure code extensions for RK3399 in the future.

As rk3399 TRM1.1 document show, when set PMU_CRU_GATEDIS_CON0/1
register, it need set the write_mask bit (bit16 ~ bit31), but as
we test, it not need it. So need to correct the setting way, otherwise
it will set wrong value to this register.

We found that the DUT will be hanged if we don't set the bit_1 of the
PMUCRU_GATEDIS_CON0. But, from the TRM, there is weird that the bit_1
is set the clk_center1_gating_dis, not clk_pmum0_gating_dis. Is the
TRM incorrect? We need to check it with the IC team and re-clean the
commit message and explain it tomorrow.

This patch do following things:
1. Request hresetn_cm0s_pmu_req first then request
   poresetn_cm0s_pmu_req during M0 enable.
2. Do not diable M0 clock for ddr dvfs.
3. Correct the clk_pmum0_gating_dis bit, it is BIT0 not BIT1
4. do not set/clear hclk_noc_pmu_en in M0 code, it does not relate
   to the M0 clock.

This fixes a hang with setting the DRAM rate based on a race condition
with the M0 which sets the DRAM rate. The AP can also starve the M0,
so this also delays the AP reads to the DONE parameter for the M0.

We used dcf do ddr frequency scaling, but we just include a dcf
binary, it hard to maintain later, we have M0 compile flow in ATF,
and M0 can also work for ddr frequency scaling, so let's use it.
