[PATCH] wifi: brcmsmac: Remove const from tbl_ptr parameter in wlc_lcnphy_common_read_table()

A new warning in clang [1] complains that diq_start in
wlc_lcnphy_tx_iqlo_cal() is passed uninitialized as a const pointer to
wlc_lcnphy_common_read_table():

  drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_lcn.c:2728:13: error: variable 'diq_start' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
   2728 |                                                      &diq_start, 1, 16, 69);
        |                                                       ^~~~~~~~~

The table pointer passed to wlc_lcnphy_common_read_table() should not be
considered constant, as wlc_phy_read_table() is ultimately going to
update it. Remove the const qualifier from the tbl_ptr to clear up the
warning.
