Sergei Shtylyov 758e285fac [MIPS] Alchemy: work around clock misdetection on early Au1000
Work around the CPU clock miscalculation on Au1000DA/HA/HB due the
sys_cpupll register being write-only, i.e. actually do what the comment
before cal_r4off() function advertised for years but the code failed at.
This is achieved by just giving user a chance to define the clock
explicitly  in the board config. via CONFIG_SOC_AU1000_FREQUENCY option,
defaulting to 396 MHz if the option is not given...

The patch is based on the AMD's big unpublished patch, the issue seems to
be an undocumented errata (or feature :-)...

Wolfgang Ocker 0ec734c2b8 [MIPS] Alchemy: Fix ids in Alchemy db dma device table
0 is a valid device id (DSCR_CMD0_UART0_TX), so we can't use it to mark
an empty entry in the device table. Use ~0 instead and search for id ~0
when looking for a free entry.

Florian Fainelli f708631ac7 [MIPS] Alchemy: Fix USB initialization.
This patch fixes a wrong ifdef in the board setup code, leading to the GPIO
pin not being pulled high, and thus the USB switch not being powered at all.

This finishes the rename of CONFIG_USB_OHCI to CONFIG_USB_OHCI_HCD, which
started in 2005 (before 2.6.12-rc2), then probably because things were
working anyway for most people got forgotten.

[Ralf: Paolo's original patch didn't fix the module case, Florian's patch
only fixed MTX1 etc. so this is a combined patch plus some cleanups.]
