e1ea6db35f wifi: brcmsmac: avoid function pointer casts
An old cleanup went a little too far and causes a warning with clang-16
and higher as it breaks control flow integrity (KCFI) rules:

drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy_shim.c:64:34: error: cast from 'void (*)(struct brcms_phy *)' to 'void (*)(void *)' converts to incompatible function type [-Werror,-Wcast-function-type-strict]
   64 |                         brcms_init_timer(physhim->wl, (void (*)(void *))fn,
      |                                                       ^~~~~~~~~~~~~~~~~~~~

Change this one instance back to passing a void pointer so it can be
used with the timer callback interface.

47f0e32ffe wifi: brcmsmac: phy: Remove unreachable code
wlc_phy_txpwr_srom_read_nphy() in wlc_phy_attach_nphy() can not
return false, so it's impossible to get true value in this
if-statement. Also change those functions return types to void
since no one using it.

d5633bb2c6 brcmsmac: make const array ucode_ofdm_rates static, reduces object code size
Don't populate const array ucode_ofdm_rates on the stack, instead make it
static. Makes the object code smaller by 100 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  39482	    564	      0	  40046	   9c6e	phy_cmn.o

After
   text	   data	    bss	    dec	    hex	filename
  39326	    620	      0	  39946	   9c0a	phy_cmn.o
