sonypi driver update

Hi,

Now that a new -pre cycle is about to start, here is my latest version of the sonypi driver.

The attached patch:
* fixes a hang problem when loading the driver on (at least) a PCG-FX105k. Thanks to Jozef Kruger for reporting the problem and testing different versions of this fix.

* tests if the ACPI subsystem is not disabled before trying to use its ec_read/ec_write methods.

* fixes the hangs when enabling bluetooth (thanks to Daniel K. for the patch).

* other miscellaneous small fixes.

Marcelo, please apply.

Stelian.
