sometimes we want to just mask/unmask interrupts
without touching devctl register. For those
cases, let's introduce musb_enable_interrupts and
musb_disable_interrupts()

Whenever babble happens, MUSB controller will
drop session automatically.
The only case where it won't drop the session,
is when we're running on AM335x and SW_SESSION_CTRL
bit has been set. In that case, controller will
not touch session bit so SW has a chance to recover
from babble condition.

We want to check if that particular bit is
set. It could very well be that bootloader
(or romcode) has fiddled with MUSB before
us which could leave other bits set in this
register.

musb->int_usb already contains the correct
information for musb-core to handle babble.
In fact, this very check was just causing a
nonsensical babble interrupt storm.
With this I can get test.sh to run and, even though
all tests fail with timeout, that's still better
than locking up the system due to IRQ storm.
Also, if I remove g_zero and load g_mass_storage,
then everything works fine again.

when musb is operating as host and a remote wakeup
fires up, a resume interrupt will be raised. At that
point SUSPENDM bit is automatically cleared and
RESUME bit is automatically set.
Remove those two from IRQ handler.

As per the SAF1761 data sheet[0], the DcChipID register represents
the hardware version number (0001h) and the chip ID (1582h) for the
Peripheral Controller.
However as per the ISP1761 data sheet[1], the DcChipID register
represents the hardware version number (0015h) and the chip ID (8210h)
for the Peripheral Controller.
This patch adds support for both the chip ID values.

In the case of a trie that had no tnodes with a key of 0 the initial
look-up would fail resulting in an out-of-bounds cindex on the first tnode.
This resulted in an entire trie being skipped.
In order resolve this I have updated the cindex logic in the initial
look-up so that if the key is zero we will always traverse the child zero
path.

This patch assigns the more appropriate void* type to the mmio750 variable
eliminating an unnecessary volatile qualifier in the process. Additionally it
updates parameter types as necessary where those parameters interact with
mmio750, removes unnecessary casts and updates the type of the
lynx_share->pvReg field which is passed to the ddk750_set_mmio method.
As a consequence, this patch fixes the following sparse warning:-

When validating the mask against the amount of memory we have available
(so that we can trap 32-bit DMA addresses with >32-bits memory), we had
not taken account of the fact that max_pfn is the maximum PFN number
plus one that would be in the system.
There are several references in the code which bear this out:
mm/page_owner.c:
for (; pfn < max_pfn; pfn++) {
}
arch/x86/kernel/setup.c:
high_memory = (void *)__va(max_pfn * PAGE_SIZE - 1)

To maximize the usability of the Fast Connectable feature we should make
it possible to set (or unset) it at any given moment. This means
removing the dependency on the 'connectable' setting as well as the
'powered' setting. The former makes also sense since page scan may get
enabled through add_device even if 'connectable' is false. To keep the
setting available over power cycles its flag also needs to be removed
from the flags that are cleared upon HCI_Reset.
