pinctrl: mvebu: armada-{38x,39x,xp}: normalize naming of DRAM functions This commit makes the dram functions naming (both the name and subname) consistent accross SoC, by using: dram(vttctrl) dram(deccerr) in all Marvell SoCs. Due to the change to the name, it changes the DT binding, but these functions are not used by any in-tree Device Tree file, and are very unlikely to be used by anyone.

pinctrl: mvebu: armada-{38x,39x,xp}: normalize naming of DRAM functions This commit makes the dram functions naming (both the name and subname) consistent accross SoC, by using: dram(vttctrl) dram(deccerr) in all Marvell SoCs. Due to the change to the name, it changes the DT binding, but these functions are not used by any in-tree Device Tree file, and are very unlikely to be used by anyone.

pinctrl: mvebu: armada-{370,375,38x,39x,xp}: normalize TDM pins This commit normalizes the naming of the TDM pins accross the different Marvell SoCs. Mainly it consists in: * Removing the 'n' from signal names: 'intn' becomes 'int' and 'rstn' becomes 'rst' * Renaming the main name 'tdm2c' to 'tdm' on Armada 38x. * Change the main name 'tdm-1' to 'tdm' for one of the pins of the Armada XP The last two changes affect DT compatibility, but since the TDM interface is nowhere near being supported in mainline, it should not be considered to be a serious problem at this point.

Drivers: pinctrl: remove __dev* attributes. CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
