Subject: [PATCH 4/5] ARM: dts: lpc3250-phy3250: add at25 required properties

Add at25 required properties (size, address-width and pagesize), which
duplicate deprecated properties.

Change nodename 'at25' to 'eeprom'.

Fix below CHECK_DTB warning:
  arch/arm/boot/dts/nxp/lpc/lpc3250-phy3250.dtb: at25@0 (atmel,at25): 'pagesize' is a required property
  arch/arm/boot/dts/nxp/lpc/lpc3250-phy3250.dtb: at25@0 (atmel,at25): $nodename: 'anyOf' conditional failed, one must be fixed:
