socfpga_setup_ocram_self_refresh()
if of_find_device_by_node() succeed, socfpga_setup_ocram_self_refresh
doesn't have a corresponding put_device(). Thus add a jump target to
fix the exception handling for this function implementation.

As SoCFPGA uses the standard suspend_valid_only_mem() for its
platform_suspend_ops.valid() callback, its platform_suspend_ops.enter()
callback will never be called with state equal to PM_SUSPEND_STANDBY.

This change modifies gen_pool_get() and devm_gen_pool_create() client
interfaces adding one more argument "name" of a gen_pool object.
Due to implementation gen_pool_get() is capable to retrieve only one
gen_pool associated with a device even if multiple gen_pools are created,
fortunately right at the moment it is sufficient for the clients, hence
provide NULL as a valid argument on both producer devm_gen_pool_create()
and consumer gen_pool_get() sides.
Because only one created gen_pool per device is addressable, explicitly
add a restriction to devm_gen_pool_create() to create only one gen_pool
per device, this implies two possible error codes returned by the
function, account it on client side (only misc/sram). This completes
client side changes related to genalloc updates.

To be consistent with other genalloc interface namings, rename
dev_get_gen_pool() to gen_pool_get(). The original omitted "dev_" prefix
is removed, since it points to argument type of the function, and so it
does not bring any useful information.

Add code that requests that the sdr controller go into
self-refresh mode. This code is run from ocram.
Suspend-to-RAM and EDAC support are mutually exclusive on
SOCFPGA. If the EDAC is enabled, it will prevent the
platform from going into suspend.
Example of how to request to suspend to ram:
$ echo enabled > \
/sys/devices/soc/ffc02000.serial0/tty/ttyS0/power/wakeup
$ echo -n mem > /sys/power/state
