MIPS: BCM63XX: remove bogus Kconfig selects
Remove the bogus selects on USB-related symbols for 6345 and 6338, not
only we do not yet support USB on BCM63XX, but they also cause the
following warnings:
warning: (BCM63XX_CPU_6338 && BCM63XX_CPU_6345) selects
USB_OHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies
(USB_SUPPORT && USB && USB_OHCI_HCD)

USB_OHCI_BIG_ENDIAN_DESC which has unmet direct dependencies

Just get rid of these bogus Kconfig selects because neither 6345 nor
6338 actually have built-in USB host controllers.

MIPS: Fix execution hazard during watchpoint register probe
Writing a value to a WatchLo* register creates an execution hazard, so
if its value is then read before that hazard is cleared then said value
may be invalid. The mips_probe_watch_registers function must therefore
clear the execution hazard between setting the match bits in a WatchLo*
register & reading the register back in order to check which are set.
This fixes intermittent incorrect watchpoint register probing on some
MIPS cores such as interAptiv & proAptiv.

MIPS: Loongson: Fix random early boot hang
Some Loongson boards (e.g. Lemote FuLoong mini-PC) use ISA/southbridge
device (CS5536 general purpose timer) for the timer interrupt. It starts
running early and is already enabled during the PCI configuration,
during which there is a small window in pci_read_base() when the register
access is temporarily disabled. If the timer interrupts at this point,
the system will hang. Fix this by adding a fixup that keeps the register
access always enabled.
