Bluetooth: btmrvl: support sysfs initiated firmware coredump
Since commit 3c47d19ff4dc ("drivers: base: add coredump driver ops")
it is possible to initiate a device coredump from user-space. This
patch adds support for it in btmrvl_sdio adding the .coredump()
driver callback. This makes dump through debugfs obsolete so removing
it.
