char: hw_random: convert drivers/char/hw_random/* to use module_platform_driver()
This patch converts the drivers in drivers/char/hw_random/* to use the
module_platform_driver() macro which makes the code smaller and a bit
simpler.

hwrng: timeriomem - Fix potential oops (request_mem_region/__devinit)
Fixed oops when calling device_unregister followed by device_register
(changing __init to __devinit) and removed request_mem_region() as
platform_device_register already does this which can result in EBUSY

hwrng: timeriomem - Use phys address rather than virt
There is no ioremap'ing or anything in timeriomem-rng.c as I foolishly
used already remapped virtual addresses instead of passing the physical
address to be polled.
This patch fixes this flaw and lets developers do the Right Thing(tm).

hwrng: timeriomem - New driver
Some hardware platforms, the TS-7800[1] is one for example, can
supply the kernel with an entropy source, albeit a slow one for
TS-7800 users, by just reading a particular IO address. This
source must not be read above a certain rate otherwise the quality
suffers.
The driver is then hooked into by calling
platform_device_(register|add|del) passing a structure similar to:
------
static struct timeriomem_rng_data ts78xx_ts_rng_data = {
.address = (u32 *__iomem) TS_RNG,
.period = 1000000, /* one second */
};
static struct platform_device ts78xx_ts_rng_device = {
.name = "timeriomem_rng",
.id = -1,
.dev = {
.platform_data = &ts78xx_ts_rng_data,
},
.num_resources = 0,
};
