IDE: fix "biostimings" and legacy chipsets' boot parameters interaction.

"biostimings" cannot be hardcoded to -19, make it -8.
Code in ide_setup() assumes that everything <= -11 is a legacy
chipset name, so fe. "ide0=ali14xx ide0=biostimings" will fail
while "ide0=biostimings ide0=ali14xx" will be okay.
