misc: habanalabs: pci: Fix a variety of kerneldoc issues

hl_pci_bars_map() has a miss-typed argument name in the function
description.  hl_pci_elbi_write() was missing documented arguments.
The headers for functions hl_pci_bars_unmap(), hl_pci_elbi_write()
and hl_pci_reset_link_through_bridge() were written in kerneldoc
format, but lack the kerneldoc identifier '/**'.  Let's promote
them so they can gain access to the checker.

These changes fix the following W=1 kernel build warnings:

 drivers/misc/habanalabs/pci.c:27: warning: Function parameter or member 'name' not described in 'hl_pci_bars_map'
 drivers/misc/habanalabs/pci.c:27: warning: Excess function parameter 'bar_name' description in 'hl_pci_bars_map'
 drivers/misc/habanalabs/pci.c:147: warning: Function parameter or member 'addr' not described in 'hl_pci_iatu_write'
 drivers/misc/habanalabs/pci.c:147: warning: Function parameter or member 'data' not described in 'hl_pci_iatu_write'
 drivers/misc/habanalabs/pci.c:324: warning: Excess function parameter 'dma_mask' description in 'hl_pci_set_dma_mask'
