Note that this does not make it a complete PSCI 1.0 implementation

On the veyron board the vcc33_sd regulator is used as vmmc-supply for
the SD card. This regulator is powered in the MMC core during power on
but its value is never actually set.
In the veyron platform the reset value for the LDO output is 1.8V while
the standard (min and max) value for this regulator defined in the DTS
is 3.3V. When the MMC core enable the regulator without setting its
value, the output is automatically set to 1.8V instead of 3.3V.
With this patch we preemptively set the value to 3.3V.

The function set_default_env() sets the hashtable flags for import_r().
Formally set_default_env() doesn't accept flags from its callers. In
practice the caller can (un)set the H_INTERACTIVE flag, but it has to be
done using the first character of the function's string argument. Other
flags like H_FORCE can't be set by the caller.
Change the function to accept flags argument. The benefits are:
1. The caller will have to explicitly set the H_INTERACTIVE flag,
instead of un-setting it using a special char in a string.
2. Add the ability to propagate flags from the caller to himport(),
especially the H_FORCE flag from do_env_default() in nvedit.c that
currently gets ignored for "env default -a -f" commands.
3. Flags and messages will not be coupled together. A caller will be
able to set flags without passing a string and vice versa.
Please note:
The propagation of H_FORCE from do_env_default() does not introduce any
functional changes, because currently himport_r() is set to destroy the
old environment regardless if H_FORCE flag is set or not. More changes
are needed to utilize the propagation of H_FORCE.
