Gen1 chips use a 16 bit mailbox extension register, for upto 48 bit
mailbox commands. The newer generation chips use a 32 bit mailbox
extension register instead, for upto 64 bit mailbox commands.

Handle writing the larger mailboxes.

Add 8723bu 1T radio init table. The vendor driver indicates that some
registers need special treatment for TFBGA90, TFBGA80, and TFBGA79
packaging. However the vendor driver never actually checks the package
type, so just stick to default values here.

Smatch reports the following warning:

  CHECK   drivers/net/wireless/realtek/rtlwifi/rc.c
drivers/net/wireless/realtek/rtlwifi/rc.c:144 _rtl_rc_rate_set_series() warn: impossible condition '(wireless_mode == 256) => (0-255 == 256)'

This warning arises because commit acc6907b87a9 ("rtlwifi: Fix warning
from ieee80211_get_tx_rates() when using 5G") now checks the wireless
mode for WIRELESS_MODE_AC_ONLY (BIT(8)) in _rtl_rc_rate_set_series().
As a result, all quantities used to store the wireless mode must be u16.

This patch also reorders struct rtl_sta_info to save a little space.

passing rtl_stats by value is inefficient; the structure is over 300
bytes in size and generally just one field (packet_report_type)
is being accessed, so the pass by value is a relatively large overhead.
This change just affects just the rx_command_packet calls.

are changed.

In addition, routines rtl_rfreg_delay() and rtl_bb_delay() are

Calling synchronize_irq() right before free_irq() is quite useless. On one
hand the IRQ can easily fire again before free_irq() is entered, on the
other hand free_irq() itself calls synchronize_irq() internally (in a race
condition free way), before any state associated with the IRQ is freed.

Patch was generated using the following semantic patch:
// <smpl>

expression irq;

-synchronize_irq(irq);
