Implement a PCI bus rescan method.
Rescanning a PCI bus uses the following steps:
- Fetch the current set of child devices and save it in the 'devlist'
array.
- Allocate a parallel array 'unchanged' initalized with NULL pointers.
- Scan the bus checking each slot (and each function on slots with a
multifunction device).
- If a valid function is found, look for a matching device in the 'devlist'
array. If a device is found, save the pointer in the 'unchanged' array.
If a device is not found, add a new device.
- After the scan has finished, walk the 'devlist' array deleting any
devices that do not have a matching pointer in the 'unchanged' array.
- Finally, fetch an updated set of child devices and explicitly attach any
devices that are not present in the 'unchanged' array.
This builds on the previous changes to move subclass data management into
pci_alloc_devinfo(), pci_child_added(), and bus_child_deleted().
Subclasses of the PCI bus use custom rescan logic explicitly override the
rescan method to disable rescans.

Add support for 8-bit eMMC.
Set MMC_CAP_4_BIT_DATA and MMC_CAP_8_BIT_DATA based on the "bus-width"
DT property and reduce maximum bus frequency from 52MHz to 50MHz to match
the capabilities of the clock provider.
Tested on a BananaPi BPI-M3 (A83T).

Stop using sbrk in csh. This is a legacy interface and its use within csh
is invalid. It is used to find the size of allocated memory. As malloc may
allocate memory with mmap it will fail to take this memory into account.

Remove unportable calls to basename().
The POSIX version of basename() doesn't use a 'const char *' argument;
the function may overwrite its input buffer. Instead of copying the
input string, let's just simplify this code by using our getprogname()
function that already returns the name of the application in the right
format.
