sunxi: mmc: Properly setup mod-clk and clock sampling phases

The sunxi mmc controller has both an internal clock divider, as well as
the divider in the mod0-clk for the mmc controller.

The internal divider cannot be used, as it conflicts with the setting of
clock sampling phases which is done in the mod0-clk, so it must be set to
0 (divide by 1).

For some reason while the kernel has had this correct from day one, the
u-boot sunxi mmc code has been using a fixed mod0-clk and setting its
internal divider depending on the desired speed. This is something which
we've inherited from the original Allwinner u-boot sources, but while this
has been fixed in Allwinner's own u-boot code at least for the A23 and later
upstream u-boot was still doing this wrong.

This commit fixes this, thereby also fixing mmc support not working reliable
on the A23 (which seems more sensitive to this) and possible also fixes some
other sunxi mmc issues.

Nokia RX-51: Do not call secure PPA routine on non secure devices

Since commit 41623c91b09a0c865fab41acdaff30f060f29ad6 u-boot running in qemu is
crashing in function do_omap3_emu_romcode_call(). RX-51 board uses this function
for Cortex-A8 errata 430973 workaround (Set IBE bit in ACR) which is needed only
on real secure device and not in qemu.

This board patch just disable calling secure PPA routine on non secure devices.
Qemu implements GP device and with this patch u-boot is working in qemu again.

common/board_f.c: fix compile error when tracing disabled

When CONFIG_TRACE is disabled, linking fails with:

common/built-in.o:(.data.init_sequence_f+0x8): undefined reference to `trace_early_init'

To fix, wrap trace init calls with #ifdef CONFIG_TRACE.

While at it, remove the static inline version of the init call from
trace.h as suggested by Simon Glass, since it doesnt work.
