This commit adds a checking code when it gets -EPROBE_DEFER while
getting a clock resource. In this case it doesn't need to print
out an error message because the probing will be re-visited.

>> drivers/soc/aspeed/aspeed-lpc-ctrl.c:247:17: warning: format '%zu'
expects argument of type 'size_t', but argument 3 has type
'resource_size_t' {aka 'unsigned int'} [-Wformat=]
Documentation/core-api/printk-formats.rst suggests %pa should work for
resouce_size_t, but it did not:
%pa[p] 0x01234567 or 0x0123456789abcdef
For printing a phys_addr_t type (and its derivatives, such as
resource_size_t) which can vary based on build options, regardless of the
width of the CPU data path.
Instead cast to an integer which works as all aspeed processors are 32-bit.

The ast2600 disables the mapping of AHB memory regions by default,
only allowing the LPC window to point to SPI NOR. In order to point the
window to any AHB address, an ast2600 specific bit must be toggled.

Alignment is a hardware constraint of the LPC2AHB bridge, and misaligned

gcc warns that a mising "flash" phandle node leads to undefined
behavior later:
drivers/soc/aspeed/aspeed-lpc-ctrl.c: In function 'aspeed_lpc_ctrl_probe':
drivers/soc/aspeed/aspeed-lpc-ctrl.c:201:18: error: '*((void *)&resm+8)' may be used uninitialized in this function [-Werror=maybe-uninitialized]
Only set the flash base and size if we find a phandle in the device
tree.

Create a SoC folder for the ASPEED parts and place the misc drivers
currently present into this folder. These drivers are not generic part
drivers, but rather only apply to the ASPEED SoCs.
