mb/google/fizz: Override IccMax settings

According to Intel document #559100 KBL EDS v2.8, section 7.2
DC specifications, the IccMax setting for KBL-U, KBL-U42 and
Celeron are different. This patch sets Celeron as default SKU
in device tree and overrides the IccMax settings for KBL-U and
KBL-U42 at pre-FSPS.

+----------------+-------------+---------------+-------+-------+
| Domain/Setting |  SA         |  IA           | GTUS  |  GTS  |
+----------------+-------------+---------------+-------+-------+
| IccMax         | 6A(U42)     | 64A(U42)      | 31A   | 31A   |
|                | 4.5A(Others)| 29A(Celeron)  | 31A   | 31A   |(Default)
|                |             | 32A(i3/i5)    | 31A   | 31A   |
+----------------+-------------+-------+-------+-------+-------+

BUG=b:71369428
BRANCH=None
TEST=emerge-fizz coreboot chromeos-bootimage & Ensure the KBL-U42,
     KBL-U and Celeron SKUs are identified correctly and IccMax settings
     are passed to FSPS correctly.
