In order to make our printf more standard, utilize %ll for long long
arguments, rather than %l. This does cost a little bit in flash space
for that extra l in a couple of places, but enables us to turn on
compile-time printf format checking.
For this commit only, the semantics are such that both %l and %ll
take 64-bit arguments. In the next commit, %l goes to its correct
behavior of taking a sizeof(long) argument.

Since pretty much always, we've declared console commands to take
a "longhelp" argument with detailed explanations of what the
command does. But since almost as long, we've never actually used
that argument for anything - we just silently throw it away in
the macro. There's only one command (usbchargemode) that even
thinks it defines that argument.
We're never going to use this, let's just get rid of it.

Previously calls to hook_call_deferred were passed the function to call,
which was then looked up in the .rodata.deferred section with a linear
search. This linear search can be replaced with a subtract by passing
the pointer to the deferred_data object created when DECLARE_DEFERRED
was invoked.

During the resume sequence of S0ix EC can receive host commands early
in the resume path when LPC is still disabled in EC. Host messages
will be lost if the LPC interface with the kernel is down.
Clock control was programed to 2 which means ring oscillator is
shut down after completion of everty LPC transaction.To restart
the oscillator EC should enable a wake interrupt on LPC LFRAME number
and this mode can cause an increase in the time to
respond to the LPC transactions.
Keeping LPC always on shows minimal power impact as per datasheet
Pg.390. The impact is < 0.45mW.

TEST=Enter into S0ix and exit reliably.

When system timer stops while in heavysleep idle task,
hibernation timer maintains system time and system timer's
recovery is done with reading from hibernation timer.
If hibernation timer setting/reading is incorrect, system timer
recovery is incorrect and evenytually this will result in
quicker/more frequent task scheduling and eventually faster
sleep LED blinking at S3 and higher S3 power consumption.

Implemented mec1322's heavysleep in idle task to
reduce further EC power down on S3.
MEC1322 needs sleep-enabled for all blocks to
acheive max power down including UART.
Real heavysleep will be effective only when
console/uart is not active.
To enable this commit, board-specific commit is required.
For example, check commit, "Enabling heavysleep idle task at S3".
Test:
1. Put device into S3 mode by typing 'powerd_dbus_suspend" in Linux
shell.
2. wait at least 1 min till EC console sleeps
3. measure EC power.
Since idle task is continuously scheduled, EC will enters/exits
to/from heavy sleep mode frequently in S3 and power consumption
will be changed dynamically.
For acurate power measurement, high-sampling-rate measurement
system might be required and using DMM might not give accurate
number.

Our code base contains a lot of debug messages in this pattern:
CPRINTF("[%T xxx]\n") or ccprintf("[%T xxx]\n")
The strings are taking up spaces in the EC binaries, so let's refactor
this by adding cprints() and ccprints().
cprints() is just like cprintf(), except that it adds the brackets
and the timestamp. ccprints() is equivalent to cprints(CC_CONSOLE, ...)
This saves us hundreds of bytes in EC binaries.
