driver/arm/css: minor bug fix ...

The cpu index was wrongly checked causing it to assert always.
Since this code path is exercised only during TF test "NODE_HW_STAT",
which queries Power state from SCP, this bug was not detected earlier.

coreboot: Use generic base address ...

Since now the generic console_t structure holds the UART base address as
well, let's use that generic location for the coreboot memory console.
This removes the base member from the coreboot specific data structure,
but keeps the struct console_cbmc_t and its size member.

Introduce a new "dualroot" chain of trust ...

This new chain of trust defines 2 independent signing domains:

1) One for the silicon firmware (BL1, BL2, BL31) and optionally the
   Trusted OS. It is rooted in the Silicon ROTPK, just as in the TBBR
   CoT.

2) One for the Normal World Bootloader (BL33). It is rooted in a new key
   called Platform ROTPK, or PROTPK for short.

In terms of certificates chain,

- Signing domain 1) is similar to what TBBR advocates (see page 21 of
  the TBBR specification), except that the Non-Trusted World Public Key
  has been removed from the Trusted Key Certificate.

- Signing domain 2) only contains the Non-Trusted World Content
  certificate, which provides the hash of the Non-Trusted World
  Bootloader. Compared to the TBBR CoT, there's no Non-Trusted World
  Key certificate for simplicity.

TBBR: Reduce size of hash buffers when possible ...

The TBBR implementation extracts hashes from certificates and stores
them in static buffers. TF-A supports 3 variants of SHA right now:
SHA-256, SHA-384 and SHA-512. When support for SHA-512 was added in
commit 9a3088a ("tbbr: Add build flag
HASH_ALG to let the user to select the SHA"), the hash buffers got
unconditionally increased from 51 to 83 bytes each. We can reduce that
space if we're using SHA-256 or SHA-384.

This saves some BSS space in both BL1 and BL2:
- BL1 with SHA-256: saving 168 bytes.
- BL1 with SHA-384: saving 80 bytes.
- BL2 with SHA-256: saving 384 bytes.
- BL2 with SHA-384: saving 192 bytes.

TBBR: Reduce size of ECDSA key buffers ...

The TBBR implementation extracts public keys from certificates and
stores them in static buffers. DER-encoded ECDSA keys are only 91 bytes
each but were each allocated 294 bytes instead. Reducing the size of
these buffers saves 609 bytes of BSS in BL2 (294 - 91 = 203 bytes for
each of the 3 key buffers in use).

Also add a comment claryfing that key buffers are tailored on RSA key
sizes when both ECDSA and RSA keys are used.
