Hi All
These patches are part of a larger patch series [1] which attempts upstreaming
EXYNOS UFS driver support. There was not much activities after v5 of that
series. In between I saw there were other teams in Samsung tried upstreaming
the same, but that has not really gone anywhere.
I have taken
Some host controller doesn't support host controller enable via HCE.

In the right behavior, setting the bit to '0' indicates clear and
'1' indicates no change. If host controller handles this the other way,
UFSHCI_QUIRK_BROKEN_REQ_LIST_CLR can be used.

This makes ufshcd_config_pwr_mode non-static so that other vendors
like exynos can use the same.

Need this to maintain sizeof(struct proc_dir_entry):
Otherwise ACK fs/proc/ part.

Now the ata host for libsas is embedded in domain_device, and the ->kref
member is not initialized. Afer we add ata transport class,
ata_host_get() will be called when adding transport ATA port and a
warning will be triggered as below:
refcount_t: increment on 0; use-after-free.

This patch series are against to mkp's 4.18/scsi-queue.
1. Add driver parameter cmd_timeout, default value is ARCMSR_DEFAULT_TIMEOUT.
2. Add slave_configure callback function to set device command timeout value.
3. Update driver version to v1.40.00.06-20180504.
