With introduction of encryption it is becoming impossible to read
NVMEM contents directly from flash. Decrypting the contents each time
there is a read request creates a significant performance hit. NVMEM
needs to be rearchitecture such that there is no need to run
decryption each time NVMEM read is performed.
This patch does just that, implementation details are described in the
header comment in common/nvmem.c.
To reduce memory impact the size of NVMEM is being decreased from 16K
to 12K. This is acceptable because eviction objects stored in NVMEM
serialized now, which dramatically reduces NVMEM size requirements.
The TPM2 NVMEM size definition must be kept in sync.
Another optimization this change introduces is bypassing writing into
the flash if NVMEM contents did not change, which is verified by
examining the hash of the cached storage.
A test is added to verify that the new commit scheme works as
expected, and the nvmem test is re-introduced to the list of test ran
on each 'make buildall'.

The new code allows to replace the existing one buffer at a time
shared memory facility with a malloc/free implementation. A new
configuration option is being provided (CONFIG_MALLOC).
The names of functions allocating and freeing memory are not being
changed to allow to switch between the two implementations seamlessly.
A double linked list of buffers is used to keep track of free and
allocated memory. During initialization the entire free memory block
is considered a single free buffer. No allocations/frees are allowed
from within interrupts. The control structures are protected by a
semaphore, so allocate and free invocation could be blocking.
A test is added which randomly allocates and frees memory, continuing
until all branches in the allocate and free functions are taken.

Some chips previously defined CONFIG_I2C and others didn't. Standardize
the usage by removing CONFIG_I2C from all config_chip files and force it
to be defined at the board level. Also, make boards define
CONFIG_I2C_MASTER and/or CONFIG_I2C_SLAVE based on the I2C interfaces
they will use - this will assist with some later cleanup.

The fans on samus have a recommended minimum duty cycle of 20%
while running, but 30% in order to start. We've been using the
EC's built-in fan controller for the start requirement, but it
has a minimum fast-start duty cycle of 50%. It turns out that
that speed is noticeably noisy.
This change handles the startup with logic in the EC instead, so
that the fan only tries to spin at 30% initially (or if it drops
too much below the minimum turning speed).
