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.
