MUSB driver has been updated to separate out BSP layer
from its generic parts, as separate driver. This patch
configures the clock with the new platform driver name.

U5500 now boots from sdi0 (onboard eMMC).
Change machine type to U5500.
Adjust uart and sdi0 clock rates for u5500.
All necessary clocks must be enabled before Linux starts because
there is no clock tree support in u5500 yet.

PRCM_TCR enables the various timers in the system. This must be achieved
before any of the MTUs are usable for kernel usage. Explicit enabling of
this in the kernel makes it independent of bootloader actions.

This adjusts the clockrate for the MTU timer. On the different
UX500 variants this rate is different. The platform can also have
been set up at hardware initialization, bootloader or early init
for different clock speeds. To have the clock framework available
early so the timers can use them, the clock initialization for
Nomadik and ux500 is moved to IRQ init time. A custom per-clock
callback is added to handle special cases like this.

This solves a user-visible bug: without this patch the current
UX500 platforms will not be synchronized to wall-clock time and
the platform will drift in time.

Most machine classes want some way to register a block of clk_lookup
structures, and most do it by implementing a clks_register() type
function which walks an array, or by open-coding a loop.

Consolidate all this into clkdev_add_table().
