[PATCH] siimage: remove resetproc() method

[Sergei Shtylyov <sshtylyov@ru.mvista.com>]

The intent behind siimage_reset() was probably to hard reset the interface and
the SATA PHY but as the code writes to two reserved bits instead, it obviously
has been ineffective from the start. So, just remove it.

This was discussed on linux-ide 4 months ago already, and the libata driver
still has the same bogus code. :-|
This patch is against Linus' tree...
