[PATCH 1/2] ARM: pxa: ssp: Drop unnecessary freeing functions

[Amitoj Kaur Chawla]

Drop clk_put, kfree, release_mem_region and iounmap for
devm_ allocated data in the remove function of the driver.

Some of these changes were made with the help of the following
Coccinelle semantic patch:
@r@
expression x;
@@

(
 x = devm_kzalloc(...)
|
 x = devm_request_irq(...)
|
 x = devm_ioremap(...)
|
 x = devm_ioremap_nocache(...)
)

@@
expression r.x;
@@

(
* kfree(x)
|
* free_irq(x)
|
* iounmap(x)
)
