oneplus5: set default readahead to 2048KB

Browse source 
Android has been benefiting quicker boot from bigger readahead during
boottime than runtime. However, the boottime readahead setting is set
when init is established after treble early mount. This patch will make
readahead bigger by default so early boot can benefit from it. Readahead
will be reset by init on boot_complete.

Bug: 62413151
Test: boot walleye 100ms faster
