Export-sas_phy_enable 

mainline inclusion
from mainline-v5.16-rc1
commit 00aeaf32
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I4QKP3
CVE: NA

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/scsi/libsas/sas_init.c?id=00aeaf329a3a1ea3d3606fefa1d29f69f828bd21

-----------------------------------------------------------------------------------

Export sas_phy_enable() so LLDDs can directly use it to control remote phys.

We already do this for companion function sas_phy_reset().
