HTC Magician contains a MAX1587A voltage regulator for a Vcore supply.
The Vcore regulation is required for a CPU speed switching. This patch adds
declaration for the max1586 driver.
Notice:
- MAX1587A version does not support the V6 (USIM) output.
- A boost resistor was directly measured for a board_id 0x3a.

This patch changes fast_mode settings for the normal and power I2C
controller on the HTC Magician machine.
Connected device on the Power I2C:
- MAX1587A: working in the fast mode
Connected devices on the Normal I2C:
- UDA1380: working in the fast mode
- OV9640: bus became stuck in the fast mode
The OV9640 is not using a standard I2C protocol, but an SCCB variant. Maybe
it is not fully compatible in the fast mode. Therefore fast mode for normal
I2C is disabled. If you not using the OV9640 then you can enable the fast
mode for the UDA1380.

Some logics actually relying on the existence of FADT, currently relies on
the number of loaded tables. This false dependency can easily trigger
regressions. One of them has been introduced by commit 8ec3f45907
(ACPICA: Tables: Fix global table list issues by removing fixed table).
The commit changing the fixed table indexes results in the change of FADT
table index, originally, it was 3 (thus the installed table count should be
greater than 4), while currently it is 0 (and the installed table count may
be 3).
This patch fixes this regression by cleaning up the code. Lv Zheng.
