Davinci: tnetv107x soc support

TNETV107X is a Texas Instruments SOC that shares a number of common features
with the Davinci architecture.  Some of the key differences between
traditional Davincis and this new SOC are as follow:

1. The SOCs clock architecture includes a new spread-spectrum PLL.  Some
elements of the clock architecture are reused from Davinci (e.g. LPSC), but
the PLL related code is overridden using existing interfaces in "struct clk".

2. The MMR layout on this SOC is substantially different from Davinci.
Consequently, the fixed I/O map is a whole lot more convoluted (more so than
DA8xx).  The net impact here is that IO_ADDRESS() will not work on this SoC,
and therefore all mappings have to be through ioremap().
