The DDR calibration routines have scattered support for bus
widths other than 64-bits:
-- The mmdc_do_write_level_calibration() routine assumes the
presence of PHY1, and
-- The mmdc_do_dqs_calibration() routine tries to determine
whether one or two DDR PHYs are active by reading MDCTL.
Since a caller of these routines must have a valid struct mx6_ddr_sysinfo
for use in calling mx6_dram_cfg(), and the bus width is available in the
"dsize" field, use this structure to inform the calibration routines which
PHYs are active.
This allows the use of the DDR calibration routines on CPU variants
like i.MX6SL that only have a single MMDC port.

Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.
Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:

So introduce a mechanism for users to be able to configure
REFSEL and REFR fields as needed.
Keep all the mx6 SPL users in their current REF_SEL and REFR values,
so no functional changes for the existing users.

memory SoDIMM on this board. Moreover, tweak the initial DDR DRAM
parameters so the calibration works properly.

There is really no need to provide an empty reset_cpu() implementation,
so just remove it.

Move the configuration to the spl code.
CCM_CCOSR setting is no longer required to get audio functionality in the
