This patch fix the resource overlapping by mapping the entire dma ring cmd csr region.

Introduce a new DT parameter 'syscon-pllreset' to provide the syscon regmap access to this register which sits in the control module. If the register is not provided we fallback to the old behaviour i.e. SATA DPLL refclk will not be disabled and we prevent SoC low power states.

This commit adds a check for Dell laptops to the code for handling these extra button bits, fixing this regression. This patch has been tested on a Dell Latitude D620 to make sure that it does not reintroduce the original problem.
