drivers/asmedia: Enable AHCI for ASM1061

The ASMedia ASM1061 seems to default to IDE mode, preventing SATA drives
from working properly in Linux as it tries to load the AHCI driver for
it. From the behaviour of vendor firmware on the ASRock Z87 Extreme 4,
the mode can be changed by setting the PCI Subclass register to either
0x06 (SATA controller) or 0x01 (IDE controller). This register seems to
be read only, but can be unlocked for writing by setting bit 2 at offset
0xEC in the PCI config space.

Since the ASMEDIA_ASPM_BLACKLIST driver already existed and only matched
the ASM1061, rename it to ASMEDIA_ASM1061 and add the AHCI mode setting
code to it.

Tested on the ASUS Maximus VI Gene.
