apm821xx: disable and move kernel CONFIG_ symbols
try to reduce the kernel size by disabling and moving options from the common kernel configuration to the SATA target that doesn't have the constraints. For NAND this has become necessary because as with 5.10 some devices outgrew their kernels. Though, in my tests this didn't help much: just a smidgen over 100kib was saved on the uncompressed kernel. ... running make kernel_oldconfig also removed some other config symbols, mostly those that already set from elsewhere or became obsolete in the meantime.
