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 the call to trace_early_init() with #ifdef CONFIG_TRACE.

Implement a feature to allow fastboot to write the downloaded image
to the space reserved for the Protective MBR and the Primary GUID
Partition Table.
Additionally, prepare and write the Backup GUID Partition Table.

The fastboot continue command is defined to exit fastboot and continue
autoboot. This commit implements the continue command and the exiting of
fastboot only. Subsequent u-boot commands can be processed after exiting
fastboot. Autoboot should implement a boot script such as "fastboot; mmc
read <...>; bootm" to fully implement the fastboot continue function.

If the MMC_MODE_DDR_52MHz flag is set in card capabilities bitmask,
it is never cleared, even if switching to DDR mode fails, and if
the controller driver uses this flag to check the DDR mode, it can
take incorrect actions.

Also, DDR related checks in mmc_startup() incorrectly handle the case
when the host controller does not support some bus widths (e.g. can't
support 8 bits), since the host_caps is checked for DDR bit, but not
bus width bits.

This fix clearly separates using of card_caps bitmask, having there
the flags for the capabilities, that the card can support, and actual
operation mode, described outside of card_caps (i.e. bus_width and
ddr_mode fields in mmc structure). Separate host controller drivers
may need to be updated to use the actual flags. Respectively,
the capabilities checks in mmc_startup are made more correct and clear.

Also, some clean up is made with errors handling and code syntax layout.

The concept of a 'current bus' is now implemented in the command line
rather than in the uclass. Also the address length does not need to
be specified with each command - really we should consider dropping
this from most commands but it works OK for now.
