linux: config: Add Intel E1000e

The E1000 driver has reset issues on the QEMU PowerNV machine with POWER9 :

[   16.140708] Unable to handle kernel paging request for data at address 0xc00c000000000000
[   16.142203] Faulting instruction address: 0xc008000000aa9b0c

   msr: 900000000280b033
   dar: c00c000000000000

  current = 0xc0000000f579a200
  paca    = 0xc000000001ec0000	 irqmask: 0x03	 irq_happened: 0x01
    pid   = 13, comm = kworker/0:1

Include the E1000e as a replacement for such QEMU machines.
