in nokia_bluetooth_serdev_probe(), check the return value of
clk_prepare_enable() and return the error code if
clk_prepare_enable() returns an unexpected value.

'skb_pad()' a few lines above already initializes the "padded" byte to 0.
So there is no need to do it twice.

All what is needed is to increase the len of the skb. So 'skb_put(..., 1)'
is enough here.

Make hci_uart_register_device() and hci_uart_unregister_device() call
serdev_device_close()/open() themselves instead of relying on the various
hci_uart drivers to do this for them.

Besides reducing code complexity, this also ensures correct error checking
of serdev_device_open(), which was missing in a few drivers.

pm_runtime_disable() is called in the _close() handler.

Since we call the _close() handler on remove, there is no need to
call pm_runtime_disable() a second time.

Joe and Bjørn suggested that it'd be nicer to not have the
cast in the fairly common case of doing
	*(u8 *)skb_put(skb, 1) = c;

Add skb_put_u8() for this case, and use it across the code,
using the following spatch:

    @@
    expression SKB, C, S;
    typedef u8;
    identifier fn = {skb_put};
    fresh identifier fn2 = fn ## "_u8";
    @@
    - *(u8 *)fn(SKB, S) = C;
    + fn2(SKB, C);

Note that due to the "S", the spatch isn't perfect, it should
have checked that S is 1, but there's also places that use a
sizeof expression like sizeof(var) or sizeof(u8) etc. Turns
out that nobody ever did something like
	*(u8 *)skb_put(skb, 2) = c;

which would be wrong anyway since the second byte wouldn't be
initialized.
