[PATCH -next] mmc: core: Use DEFINE_DEBUGFS_ATTRIBUTE instead of DEFINE_SIMPLE_ATTRIBUTE

[Zou Wei]

Fixes coccicheck warning:

drivers/mmc/core/debugfs.c:222:0-23: WARNING: mmc_clock_fops should be
defined with DEFINE_DEBUGFS_ATTRIBUTE

Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files

Fixes: 703aae3d09a4b ("mmc: add a file to debugfs for changing host clock at runtime")
Fixes: a04c50aaa916f ("mmc: core: no need to check return value of debugfs_create functions")
