From: Lin He <helin52@huawei.com>

Fix some bugs in the hibmc DP driver.

---
ChangeLog:
v1 -> v2:
  - More states in HIBMC_DP_HPD_STATUS are added to the
    'hibmc_dp_get_hpd_status'.
  - The call to `hibmc_set_enable_flag()` has been moved before
    `drm_client_setup()`, specifically before the connector detection
    triggers the I2C bit operation. (sashiko-bot)
  - A read-modify-write operation has been implemented instead of directly
    writing to prevent clearing the I2C mask bits. (sashiko-bot)

Lin He (2):
  drm/hisilicon/hibmc: Modify the method of obtaining the hpd_status
  drm/hisilicon/hibmc: Add a flag to indicate whether the OS-side driver
    has been loaded
