[PATCHv2 1/9] at91: provide macb clks with "pclk" and "hclk" name

hi Russell,

I'm not saying the drivers need ifdefs, they should request both
"pclk" and "hclk" as suggested.

What I was suggesting is the platform clock setup on AT91 as:
    macb_clk
        |
        +-- hclk
        +-- pclk

rather than:
    pclk
        |
        +-- hclk
