We can have the case where u-boot is launched after some other low level
enabler, like for example when u-boot runs after arm-trusted-firmware
and/or optee. So, because of that we may need to jump the initialization of
some IP blocks even because we may no longer have the permission for that.
So, if the config option to skip low level init is set disable also timer,
board and csu initialization.

This patch adds system suspend/resume support,
when linux kernel enters deep sleep mode, SoC will go
into below mode:
- CA7 platform goes into STOP mode;
- SoC goes into DSM mode;
- DDR goes into self-refresh mode;
- CPU0/SCU will be powered down.
When wake up event arrives:
- SoC DSM mdoe exits;
- CA7 platform exit STOP mode, SCU/CPU0 power up;
- Invalidate L1 cache;
- DDR exit self-refresh mode;
- Do secure monitor mode related initialization;
- Jump to linux kernel resume entry.

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.
