qcacmn: Fix crash caused by sdio ramdump allocation

For TF sdio chip with platform driver, ramdump is
configured in platform driver. Driver can get the
virtual memory, but it can't call ioremap again.

If there is a platform driver, ramdump should be
allocated in platform driver, and if there is no
platform driver, ramdump should be allocated in
driver.
